I need to go to Forms Mode because I can't figure out what fields to enter in the interactive mode TurboTax to get the right numbers in the tax forms. TT says to do that I have to download TurboTax Desktop. It says, "Follow these steps to amend your 2020 return." The first step is "Download your .tax file." The next step is to download TT Desktop. Finally, Step 3 is to open the .tax file.
If you can tell me how in TurboTax Online to get a prior year rental real estate loss into Form 8582 line 1c but not have that amount get added to line 1b as well, then I wouldn't have to download the software.
