Having the same problem. My TT and CK account have always had the same email and I got the RA last year no problem.
Even went as far as to change my email address to another account and still no dice. Tried chrome browser, and brave browser. Going to try on my PC one more time but I'm also getting the error that my forms aren't ready to file, that they won't be ready until 01/19... It is 01/19 and it is 12:30pm. So idk if that has something to do with it, but this is extremely annoying as I paid $150 cash to file
