Hello athlit,
Since I do not know who is the payer of 1099-NEC ( your employer or other entity), and need more info. about type of work before I can tell if this income should be subject to FICA taxes or not, here is general answer. Select the closest desc. that matches your line of work. If nothing matches, you can always select "Other". Desc. do not have impact on your return. You will still have to pay FICA (SS and Medicare) taxes on it and TurboTax will calculate correct amount.
If 1099-NEC is bonus from employer, it should have been reported on w2. You might be able to use form 8919 to report income.

Thanks for contact and hope this info. is helpful.
