I'll try to be short & to the point. I misplaced a stimulus check that I found the day after it expired. Already filed return for 2021. Received notice from IRS about it, letter stated to contact for replacement; they're unable to replace and to file an amended return. I don't know how to add that check to my amended return though. I never had to do an amended return. Finally, is it too late for an amended return to be filed by me? I will have help if I do it by paper. Thank you all in advance
