Tax law changes

OK, so the Purchase Date was the day we wrote our check: 2/13/2018

The sale date should be the date of the final check that we received? 12/17/2021

 

I have received a K-1 for 2018, 2019, 2020, and 2021 and have entered the requested information from these K-1 forms every year in TurboTax. However, this is the first final K-1 I have received, and since this limited partnership has ended (since the land has been sold), TurboTax is requesting this additional information.

 

Are there instructions on how to fill out the TurboTax form requesting the Regular Gain/Loss and AMT Gain/Loss? I have no idea what to put on that page.
