Hi - I have amended a 2021 return that was filed electronically last year.  I cannot get the electronic 1040X to transmit.  Though I said "Yes" when transmitting to knowing that it was a duplicate tax id, upon converting and transmitting I get an error message "Duplicate return.  The SSN for the selected return is identical to that of another return in your Electronic Filing HomeBase view which had been e-filed.  Please open this return, modify the SSN so that it is unique and reselect the return for conversion/transmit."

What do I do?
