Filed when I wasn't required to and filed incorrectly. I'm losing sleep over this

Hey everyone,

​I’m currently dealing with a bunch of anxiety regarding my 2025 tax filing and how it might impact my future N-400 naturalization/citizenship application down the line. I really need some peace of mind or at least some next steps.

​Here's some context:

I was an international student on an F1 visa for most of 2025. In the fall of 2025, I adjusted status and became a Lawful Permanent Resident (Green Card holder). I had absolute zero income for the entire year of 2025. No U.S. income, no foreign income, nothing.

Because my income was $0, I legally fell way below the gross income threshold and wasn't required to file a federal or state return at all. However, out of caution and wanting to start a paper trail once I got my Green Card, I went ahead and paper filed a standard resident Form 1040 (and state taxes) with all $0s. ​ I recently realized that because I transitioned mid-year, the IRS technically considers me a Dual-Status Alien for 2025. By filing a standard Form 1040, I accidentally treated myself as a full-year resident alien. I also didn't file Form 8843 to exclude my student days because, well, I filed a 1040 instead. The deadline for that for no income is coming up, so maybe that could be fixable?

​I know the mathematical outcome is identical ($0 owed to the government either way), but I'm scared I might run into issues when I eventually apply for naturalization.

​Should I be losing sleep over this? Do I need to go through the process of filing a paper amended return (1040-X) just to turn a $0 resident return into a $0 dual-status return + filing a f8843? How should I handle the "Have you ever failed to file a required tax return" question on the N-400 since my income was below the threshold but I filed a $0 resident return anyway? Any advice to calm my nerves would be greatly appreciated.
