Get your taxes done using TurboTax

When you mark the box for sporadic activity - TurboTax will report the 1099-NEC under Miscellaneous Income which will not generate self-employment tax.    If the income was received for doing work, the income should be reported on Schedule C, which does generate self-employment tax.   

At the end of the 1098-T entry section, you can enter other scholarships, grants, and fellowship income that was not reported on the 1098-T.   Entering the income there also moves it to Miscellaneous Income.   You have to click through the Education Credits section, and you will come to a screen titled Scholarships and Financial Aid.    You can enter the income there also.
