Your recommendation should go to the top, is the only thing that works (and I have tried every stupid idea that Intuit is suggesting).
Installed TT 2022 (Premier w/ State). Pointed to 2021.Tax file, never got an indication that the read was successful and that it would use some of that info to start new return (Seemed weird at the time, but did not make much of it).
Started return, saved, closed program, came back later, tried opening 2022 return, "corrupt file" message.
Started brand new return, saved midway, closed program, came back later, same error message.
Uninstalled, rebooted, re-installed, read 2021 return, started new one, saved, closed, reopened, same error message.
Installed in a 2nd computer, same steps, same results.
Re-downloaded program, re-did all the steps same crap, "corrupt file".
Moved ALL the TAX files from computer, uninstalled TT, rebooted, reinstalled. Started new return, no old files to read (removed EVERYTHING to a portable drive), added some data to return, saved, closed file, reopened, NO ERROR.
Something is really screwed with the importing script, that is the only common thing (I do not want to hear about windows updates, antivirus, cosmic rays, or anything else).
To you Sir with the recommendation to move ALL TAX files out of the PC where TT is running, I wish you well, you are a true HERO. I was about to throw my PC out the window you have saved me from a total meltdown.
To Intuit: FIX THE FREAKING SW.
