After you file

No, you do not need to fix anything as the IRS will reconcile your filed information based on what they have on file, which would be the payment that was sent out to you. Should they not catch it in time before processing, you still do not have to file an amended as you technically made no mistake/error/omission. They sent the check out to you either to the wrong address or far later than they stated they would. You followed all proper protocol.
