I don't have a schedule E on my 2020 or 2021 returns, Did I converted to personal use? want to do 1031 exchange

Trying to sell a rental condo using  1031 exchange. I didn't realize I could have claimed depreciation for the 2 years it wasn't rented due to repairs and COVID. For my 2020 taxes I only show schedule E for my other rental. I think I must have chosen that it wasn't rented or available? I can't find on my turbotax forms where that question would be listed, but when I tried to amend it still didn't ask me about that property. I guess that means I changed it to personal use. NOW I want to do a 1031 exchange this year. Can I go back and undo changing it to personal use? Is it possible I chose something on my 2019 returns because it was only rented 6 months in 2019?

 

The other option is to edit my returns to convert it back to rental in 2021 by amending my return and skipping 2020 entirely. Do I need it to have been a rental for a certain amount of time to do the 1031 this summer.?...Any advice
