We received a 1099-NEC after our taxes were filed from a company worked for for a trial period before they brought him on full time. What do I need to do to rectify this?

I didn't realize we'd be getting the 1099-NEC because I thought that work was from 2020, but I was incorrect. The company that issued the 1099 was the same that issued my w-2, (but turbo tax is now making us file self-employment and pay a substantial amount of money to them just to amend the taxes with this form. I want to pay the government what we owe, but paying this amount to turbotax makes no sense. We already paid a substantial amount out of pocket to turbotax and I'd love not to pay a lot more just to fix a mistake. I'm also concerned about late fees and penalties.) Basically, I'm asking if I need to just file an amendment and suck it up about the fees, or if there's any other option. Happy to give any more information if needed. Thanks!
