I upgrade my MAC recently.
When I prepare 2020 tax, only personal information transfer from 2019 tax. All rental property information and data don't transfer. I open 2019 tax software, my tax form shows e-file successfully. How can I fixed it?
If it opens in the 2019 program, Then save it again with a name and place you can find. Go to File - Save As. Then start a new 2020 return and transfer from the new 2019 file.
Or maybe last year you marked the rental as sold or final? See if you can find a checkbox for that in 2019. Don't know about rental on Schedule E but you can on Schedule C.
