I assumed the amount was in box 3 of the 1099-Misc. If it is in box 7, it may be self employment. Who paid you this money and why? If it's your employer, then it amounts to taxable compensation and that is subject to FICA (social security and medicare tax). It sounds like your employer wants you to pay both the employee and employer share of FICA.
That said, even when the amount is in box 7, folloing those interview answers will put it on line 8 of Schedule 1, not schedule C (self employment). I just tested it.
