You may have it in your program if you entered a form 1099-NEC or 1099-K. The income reported on those forms is often treated as self-employment income. You can review those entries and look for a question regarding the activity it was from and modify your response to indicate that it wasn't from self-employment income.
If you didn't enter a 1099-K or 1099-NEC form, you may be able to delete the schedule C by following these steps:
Click on Tax Tools in the left menu bar
Click on Tools
Look under Other Helpful Links and choose Delete a form
Look for the schedule C in the list of forms and delete it.
