Get your taxes done using TurboTax

Exactly the same :

"Looks like we’ve run into an error.

We’re sorry but we need to close TurboTax." etc, etc.
I tried calling Intuit helpline, spoke to a very nice lady who had no idea what the problem was: "it works on Windows 11" - Duh!
I'm guessing their tech guys are all on Windows 11 and assume everyone else is, except Win 11 needs a computer upgrade to work, and I ain't gonna do it.
