The IRS website has a fillable 1099 form for both the NEC and the MISC forms. Just go to the IRS.gov website and enter the corrected information on the 1099 form there and then print the new 1099. I'm not sure how they want you to submit it though. That's what I did for the one 1099-MISC form that I had to do. Then I submitted it electronically through the IRIS file system along with the 1099-NEC forms that I had to submit. Everything printed perfectly on the website form. Hope this helps.
