OK...I finally got it to work but I had to go by it a slightly different route.
On the page where it says to enter your wages, I kept deleting my 1099-NEC information. The page would show it was gone, my refund would recalculate and everything seemed good. When I reentered the info, I would still get the error for the Schedule C. When I put in 1099-NEC in the search and jumped to that direct page, it had listed several of the 1099-NECs that I entered and thought I deleted. I deleted them from that page and was finally able to reenter the information again and the return was accepted.
