Thank you for this useful info. I m sending today my 1040-X because I have been filing my taxes through Turbotax but turns out it shouldn't be used by non resident aliens as I am. As from instructions, I'm adding to the 1040-X also a copy of the wrongfully originally submitted 1040 and a copy of the amended 1040-NR-EZ.
3 questions:
1) address. Shall I still to the Department of the Treasury, Internal Revenue Service Austin, TX 73301
I also found this address: Austin - Internal Revenue Submission Processing Center 3651 S IH35, Austin TX 78741. They are slightly different. Which one is the right one?
2) shall I wait first to receive an answer from Internal Revenue Center before filing for the 2020 taxes? If not, can I file the 2020 taxes on Spring Tax by uploading the amended 1040-NR-EZ?
3) Concerning the State Tax Return, I cannot help but noticing that it would have been a slightly different amount if I would have filed through Spring Tax instead of Turbo Tax. How can I amend that? And again, as for the 2020 taxes, shall I upload on Spring Tax the 2019 Spring Tax State Tax Return (which I didn't submit) or the one that I actually wrongfully originally submitted through Turbo Tax?
Thank you for your most appreciated help.
