Thanks for the quick response. Luckily, in this case there was no withholding.
However, the link provided has instructions to the issuer of the 1099 NEC on how to send their information to the IRS. If you go there, then you get to https://www.irs.gov/pub/irs-pdf/p1220.pdf which instructs the issuer to send in a corrected 1099-NEC. (and does not provide guidance to the recipient, or say anything about withholding. Is there a different reference I should look at?
