I have the same FPYMT-071-01 rejection notice when amending my 2023 1040 return.
I tried the transmittal date and different subsequent dates, but each time it was rejected with the FPYMT-071-01 notice.
Any update on this issue?

UDATE: I checked the online IRS account. It shows a payment for the original 2023 return 02/28/24, so it seems that the IRS has processed the original return.
