Yeah, my turbo tax kept showing as a capital letter, but it was registered as a lower case. Once I went to sign back in (after changing my email to all lower case letters) it sent a code to my email to verify it. So it definitely did something and helped because before I did those steps, I was in a constant loop of that error message I try 8-10 times. I even signed out and signed it still the same thing. Soo it definitely helped! Because once I did all those steps I signed in, and it triggered that error twice and then on the 3rd try I was able to transmit my return. So it definitely helps & does something especially when multiple people are having success stories after giving it a try.
