Are you on Windows or Mac? Before you open your return make a copy of your .tax2021 file and give it another name. Like in Windows find the .tax2021 file (it should be in your Documents in a Turbo Tax folder). Then copy it and give it a name like Test 2022. Or add FINAL or FILED to your original return file. Don't play around in your real return.
The first thing I do after I install the program is turn off automatic updates so it doesn't update every time I open the program. Then I update when I want. To change the Windows program Update Preferences settings go up To Online - Updater Preferences
