Also, attach any schedule or formrelating to the change. This includes any additional or corrected Forms W-2 you received after
you filed your original return. For more information, see the 1040X
instructions (link included above).
For example, attach Schedule A (Form 1040) if you are amending Form 1040 to itemize deductions. If you are amending your return because you received another Form W-2, attach a copy of the new W-2.
