Get your taxes done using TurboTax

Try going back to the 1099-MISC input screen.  To do that:

1.       Click Federal on the left-hand side menu.

2.       Click Income across the top.

3.       Scroll down to Self-Employment and click Show more.

4.       Click Start or Revisit by Income and Expenses.

Go through every 1099-MISC that you have, and make sure boxes 15 through 20 are blank.

It's possible, too, that the 1099-MISC was put in somewhere else besides your Schedule C.  On the Income & Expenses side of Turbo Tax Self-Employed, you'll see Income from Form 1099-MISC.  It could be there.
