I made an error in 2020 tax filing forgetting to report interest payment for my rental property, which will affect my passive loss carry over.
Now that I'm filing for 2022, and I want to amend 2020 and 2021 filings. Should I:
1. E-File 2022 assuming numbers for 2020 and 2021 have been correct and mail in 2020 and 2021 amendment on the same day, or
2. E-File 2022 assuming numbers have not been corrected, then amend all three years 2020, 2021 and 2023?
The main concern here is I have to mail amendment, and it can take the IRS 16 weeks to process them, if I file the 2022 tax return with the amended numbers, the passive loss carry over will not match previous years before IRS processes my amendment which will come later.
