1099-NEC

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:

1. Open or continue your return in TurboTax
2. Search for self employment income (use this exact phrase, don't add a hyphen) and select the Jump to link at the top of the search results
3. Answer Yes on the Did you have any self-employment income or expenses? screen
4. When you get to the Let's enter the income for... screen you can enter the payments as "check" or "cash" under Other self-employed income.

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.
