If your W-2 has the "statutory employee" box (box 13) marked in TurboTax, you will be asked to link the W-2 to Schedule C. If this was an error and should not have been checked, then edit the W-2 and uncheck the box.
To go back to your W-2, from within your federal return, select the search icon at the top of the page and search for W-2 and select the Jump to link.
