I am repeatedly having an error pop up about a 1099 NEC and Schedule C. However, when I edit everything (over and over), it still comes up. Help, please?

I have deleted and re-entered the 1099 NEC. There is a line on the error that something is supposed to appear from Schedule C in a worksheet. The income from the NEC appears and the line appears to be editable but I have no idea what goes in there. Caught in a loop and don't know how to get out of it. ARGH!
