The answer to this issue depends on why TurboTax is looking for a Schedule C. If you are seeing this message in Review, what else is being shown on the screen with the Review message?
Did you enter income from a Form 1099-NEC or 1099-MISC? Or a Form 1099-PATR? Depending on your answers to the questions in those sections, TurboTax may conclude that you have a business.
