My 2019 married filing jointly return was mailed on October 13, 2020 via certified mail and return receipt requested. Living in Texas, it was mailed to the Charlotte NC (P. O. Box 1214) address, I received the return receipt back stamped as received on November 10, 2020 and check with amount owed cleared my bank.
Since this return involved an address change, I attempted to follow up on MyIRS account in mid February, 2021 as we had not received the EIP-3 payment. Seeing nothing recorded on the IRS website except a credit for the money paid, I then filed a form 8822 with the address change, also by certified mail and return receipt requested (which was also received back).
I now see a communication from IRS indicating that they have no record of a processed tax return for 2019.
Do I the second copy back to the Charlotte NC PO Box where it will get processed with all other 2020 returns in progress? Meanwhile my address is not updated and EIP-3 payment will most probably have to be declared on 2021 return as not received. So frustrating.
