"mail a ton of paperwork to the IRS. "
@steyaert
How to file:
Do not include your old 1040 nor your revised 1040 because the Form 1040-X reflects any changes there and becomes your new tax return.
Include any new/corrected tax document only if it shows federal tax withheld, and include in order only those Sequence Numbered tax forms and schedules that changed or were added due to your amendment.
Attach the schedule or form(s), if any, that you used to figure your revised tax (LIne 6). Don’t attach worksheets.
Mail to the address shown for your location in the most recent Instructions for Form 1040-X.
