TurboTax is telling me I need to upgrade because I am reporting a sale of a flipped property. Except I'm not and it won't let me change anything.
I don't know, but I hope you get an answer because I am having the same problem.
@krys0886 If you are already in an upgraded version, you won't be able to downgrade in TurboTax. We advise beginning a fresh return with no imports.
