"who have a 1099 Misc or NEC of a fairly minimal amount and no expenses"

These informational forms are only required in certain circumstances, but people can have made more money than this in the endeavor. You could make a million $ from being a notary and would never get a 1099-NEC for the service. It still is reported.

1099-Misc is for different reason than 1099-NEC. NEC would be Schedule C, but MISC might be royalties or rent. Are you trying to enter Rent as subject to Self-employment tax?
