Your question is unclear. Did you prepare a 1099NEC for someone who performed work or services for you? Or did you receive a 1099NEC for work or services YOU performed for a business or an individual? What are you trying to do? Were you self-employed? Are you trying to file by mail?
If you prepared the 1099-NEC and need to mail the red copies to the IRS with Form 1096, follow this link to get the address for your state.
If that is not what you meant, please reply back with more details about what you are trying to do.

The various 1099 forms are reported to the IRS on IRS form 1096 Annual Summary and Transmittal of U.S. Information Returns here.
The instructions and IRS mailing addresses are found on the form.
