Double-click in the box next to where it says 'Schedule C' and see if it'll link to your Schedule C.    When you entered the 1099-nec, you are asked to ''describe the reason''.   What did you put for the reason?  And on the next screen, you were asked about uncommon situations.  Did you select ''None of these apply''?   Or something else?    

Search for 1099-nec to go back and review your entries.   The screen after the uncommon situations question, will let you to link your form to whatever you used as a description.   See images below.  In my example, I used ''testing'' as the line of work.    I'll link the TurboTax phone number here if this doesn't work for you.  

Once the 1099-nec is linked to a Schedule C, the error will go away.
