"I do not know. sorry"

We cannot help until you can answer this. You might be Lost on the internet.

You posted on a peer community forum titled Practice Advice; that means you would be a professional tax preparer with a business "practice" for client tax returns. The 1099-NEC you prepare would be for your business' and your clients' reporting needs.

Were you using TurboTax last Year? Are you asking about personal 1099-NEC issued to you by people that paid you in 2020? Which "old files" from "last years" are you asking about: your own income tax returns?

At least give us some perspective, if you would like some direction.
