I’ve done all those things last year and this year. I’m familiar with all the tips of deleting all the relevant files in the ~Library directory, fully uninstalling/reinstalling the app, etc.
In 30 years of using Intuit Mac tax software (going back to Macintax for those who May remember it), I’ve never had issues until last year when Mac OS 11 and TurboTax didn’t play nice.
Given this 15 and counting page thread of complaints, along with Intuit admitting to me on my support call that it is unreliable on Big Sur (yes, it obviously works for some), the problem is not the end user in this case.
I ran it on my Catalina VM and it works, but was given a pop up upon launching the app that only Big Sur would be supported for future products after this current release of 2022 TT.
