I am mailing the 2020 return tomorrow, just under the deadline to forfeit the refund. The 2021 return will be mailed shortly with a check for the $20k I owe, or whatever the balance is after applying the refund from 2020. I owe $2k for 2022 and have a loss in 2023 to apply to subsequent returns, so my only concern at present is 2021.
