Scroll down to 'Business Items' in the 'Wages and Income' section and click 'Start' next to 'Business Income and Expenses (Sch C)'. You don't need a schedule F because you don't have a farm so this will walk you through being able to put in any expenses that you had in order to earn the money on the 1099-NEC.
I had already entered the 1099-NEC, but my last detail to review before I submit my return is still asking me to "remove the link that is not applicable" in the 1099-NEC form. There is not text in the Schedule F, only in the C. It is saying to "double click to link to" with the two boxes for Schedule F or C, but I can't double click on anything in the section.
You're going to have to go back to the 1099-NEC that you have entered on the federal return and link it to the schedule C from there. Then you need to go to the schedule C and complete it as I've detailed above.
