Junebug, I had the same problem starting last Sunday (4/2/23) as well. I was on my PC at the TT website and this infuriating message kept popping up. Usually when I clicked on "take me to where I left off." It kept giving me this error through today.
I just made my own post somewhere on this forum but I resolved the issue by downloading TurboTax app on my cellphone.
I was able to sign in today to my existing account and finish and file my return.
So if you are on a PC, try the phone app. I have no clue why it worked but it worked.
And I will join the chorus of those telling the mods here to stop sharing the ridiculous advice to 'clear your cache" or "try a different browser" as a solution to this particular problem. It's simply not helpful.
INTUIT THIS PROBLEM IS AT YOUR END, NOT OURS!!!
