You'll need to complete form 1040X for amending returns. In the top portion, you can choose what year you are amending for. You will then need to complete the 1040NR for that year.
You will need to print and mail the IRS the following:
- Your Form 1040X
- Your Form 1040NR or 1040NR-EZ with “AS AMENDED” written on top of each page, and
- a copy of the Form 1040 you originally submitted with “COPY OF ORIGINALLY SUBMITTED” written on top of each page.
Mail these to the address provided in the IRS 1040X instruction.
