irs cashed my check in april 2020. lost my 2020 return. I mailed the return in 4/2020. i received a letter 12/21 that the irs needed a copy of my 2020 return. I sent it 12/31/21 by certified mail to kansas city MO. they received and signed for the return 1/5/22. i completed my 2021 federal tax return 2/13/22. I always use turbotax to prepare my taxes. i tried to submit my 2021 return electronically. it was rejected because my 2020 has not been processed. i have called the irs number [phone number removed] and can't get through. please advise. thank you
