How do i add my TER ID: 68775 to my new account

...on your profile. You don't need to connect your ID to your new account. Any new reviews you get will automatically go onto your 68775 profile as it's the only profile you have.  

I do recommend you now use the Problem Report button on your profile and have TER update the things that need it. (such as age, phone number, e-mail, services) You may want to use the Contact Us link at the bottom of any page to notify TER of the updates since there may be several things you need to make. The Problem Report button is for quick simple things.

...that TER gives 2 free VIP days for every problem report submitted by a hobbyist?  You must really like paying for VIP.
