Quarterly Estimates on 1099 — Screwed for next year?

Hello! I am navigating taxes and know almost nothing about them, so forgive me.

Background: I have a full time job that i got in March of last year (I was freelancing before then for about a year after a layoff). I didn't self-report my taxes and got the warning letter after I filed for 2024. After I got my new job, I paused my freelancing but kicked it back up in August-ish, making around $4k since then. Last year I get a 1099-NEC from this freelance client.

Am I screwed for filing for 2025 since I haven't self-reported yet? I'm not so worried about getting a penalty, more about getting audited or something lol. I know about the safe harbor rule and am trying to figure out if the taxes being withheld by my current employer might be able to apply?

Thanks in advance!
