I mistakenly filed the wrong tax return form for 2024. My husband and I were not U.S. tax residents, as we moved to the U.S. in July 2024. This means we should have filed Form 1040-NR. I answered all the questions correctly, stating that we hadn’t lived in the U.S. for more than 6 months, but the software still generated a regular 1040 resident return.
I understand that I now need to file Form 1040X along with Form 1040-NR, but I have no idea how to do this through this website, and I haven’t been able to find a way to do it on my own.
