It sounds like the form that you have is not a 1099-NEC. Box 3 is not used on a 1099-NEC. That's why there's no box 3 in TurboTax. Does your form actually say 1099-NEC on it? Or is it perhaps a 1099-MISC, which does have a box 3? If it's a 1099-MISC, enter it in TurboTax as a 1099-MISC, not a 1099-NEC.
What is the form for? Where is the income from? Why did you get the income?
