This answer from @AliciaP1 has the steps that will let you enter the income from the 1099-NEC:
You can report the sum total of the income you received and report it as other self-employed income. To do this please follow these steps:
The details of the 1099-NEC are not necessary as long as you report all the income you received.
I would just enter it as Other self employment income or as Cash or General income. You don't need to get a 1099NEC or 1099Misc or 1099K. Even if you did you can enter all your income as Cash. Only the total goes to schedule C.
