In the Desktop program you can switch to Forms Mode and open a 1099NEC and fill it out. It will populate your return. It will show up on the business income page on the 1099Misc line. That will probably be fixed when they update that part of the program.
If you have the Online version or even in the Desktop program just enter your total business income as Cash or General. You don't need to enter the actual 1099Misc or 1099NEC. Only the total goes to schedule C line 1.
