Wrongly filed 1040NR instead of 1040 where to send 1040X?
I am amending my tax return by 1040X. I had originally filed 1040NR but later I realized that I should have filed 1040. When I first filed my 1040NR, I was living in Georgia. Now I am in the state of Washington. In the instructions manual of 1040X it says: "If Form 1040X includes a Form 1040NR or 1040NR-EZ, mail it to the Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, USA."
What does it mean for 1040X to include form 1040NR? Does it apply to me? Where should I send my 1040X?
Thanks.
