Hopefully this helps someone. 1 of the 1099-NECs had the withholding blank, so I left the box blank. Turns out you have to put a "0" in the field. I deleted both 1099-NECs and re -entered them with zeroes for withholding, then the 1099-NECs carried over properly to the Schedule W form. Now I have to figure out how to submit an amended state return.
When the TT software checks for errors, I think it should flag a missing entry.
