Your status may not be self-employed but Form 1099-NEC is for non-employee compensation so it is treated as a Schedule C self-employed. You should select to put the information on a Schedule C. This will carry over to the 1040 and will be reported as a ($10,000) and if you entered the information on the 1099-NEC correctly the ($1,000) will report correctly.
I would assume next year you will receive a W-2 as you have in the past.
