I've amended the return to correct form 8606 for the 2024 return. However, when getting to the end of the amendment flow in turbotax (i.e. after putting in the reason for amendment), it gave me option to correct account / routing number, as well as selecting a date for IRS to deduct the new owed amount. I did this, but I kept getting a message saying "Account number invalid for electronic filing" Despite triple checking the number and making sure there weren't any hidden/special characters. When I hit continue, there was a screen to print forms, with step 2 saying "Send amended forms to IRS and include any relevant checks."
It's not clear whether it actually e-filed the amendment or not. There is a "Check E-file status", and it says 2024 Federal amended return was accepted, however this is the second time I've amended, so it's not clear if thats referring to the first time or this most recent time.
