I'm going to assume you have been reviewed by a client here on the TER site since you asked about editing your profile. That's the only way you would have a profile. If you do have a profile there is a button labeled "Report a Problem" (along with some others) near the top of your profile and a little to the right. You can click that button and tell TER admin what needs to be corrected on your profile. Your TER ID (ID#) is just under your name on the left of your profile. If there is a lot of information on your profile that needs editing you should use the "Contact Us" link at the bottom of any page to inform TER admin what needs correcting.

Now just in case you don't have any reviews here on TER I'll give you what you need to know about your profile and TER ID# based on that situation. If you don't have at least one review here then you don't have a profile or a TER ID#. Here on TER your first reviewer sets your profile (Which is why it often needs editing.) and once it's approved by TER and posted you will have a profile and TER ID#.

This next part is long but believe me it's easier than gathering all this information from it's various places on the site.

Everyone when they join TER is a basic member. There is no "Provider" membership, provider page, etc. (Even though you may have clicked register as a provider when you signed up [joined].) The way to let others know you are a provider is to post ads on your TER regional ad board, post comments on your regional discussion board (Don’t make these discussion board posts about you like an ad. They will be disallowed. Make them pertinent to the subject.), and participate on the Photo Only board. Check out the Self-Help Center for the guidelines for posting ads and how to post photos on the photo only board. The Self-Help Center link is on the upper right of most of the discussion boards under the red and white life preserver. It’s also at the bottom of the list of Quick Links on the left of the My TER page. See the My TER tab at the top of the page. Read everything there even the stuff for the guys. It's good to know all you can.  
 
You can pay for a VIP membership. It will give you full access to all TER has to offer but it won't distinguish you from any other member. The things I mentioned above and the link spoken about in the next paragraph will do that.  
   
Once a guy has seen you, written a review of you, submitted it to TER, it's been approved, and posted you will have a provider profile page. Your first reviewer creates this profile when he fills out your information. You will then be assigned a TER provider ID number. It will be on the upper left of your profile. (You can contact TER and correct anything the guy got wrong on your profile or didn’t know.) Now you can contact TER and request they connect your newly created profile with your TER handle/user name (MsMaddison). Contact them using the e-mail you signed up with. Their address is [email protected]. (If you like you can use the “Contact Us” link instead. It’s at the very bottom of any page.) This will give you the free limited provider VIP membership. It will also give you access to the TER PM (private mail) system and allow you to read your reviews in there entirety. TER will place a link which says "See my TER reviews" under your handle whenever you post on a TER board. Guys can click the link and be taken to your profile page and check you out. The provider VIP will also give you access to the provider functions on TER such as being able to white list clients.  There is a Provider's only discussion board. You have to have 3 reviews and establish yourself on the boards then request that TER give you access to it.

If you think you already have reviews here you can search to see. Click the reviews tab at the top of the page. Then click search reviews (just under the reviews tab). Scroll down to the 4th section titled Provider's Contact Information and enter your info. The basics should be enough. That is your provider name, phone number, e-mail, city, and country. Next scroll to the bottom of the page and click the big search button. You will be taken to a page containing the results. If you have reviews your name along with others will be listed down the left margin. Click on your name (in teal colored font) and you will be taken to your profile.

One other bit of information is your posts on any board right now are moderated. TER admin has to check them and approve them before they show up (post). Every new TER member goes through this. After you have posted on the boards for a while you can contact admin using "Contact Us" at the bottom of any page and request to be un-moderated.
