I think the correct option is to delete the business and schedule C entirely. If you did not receive a 1099 for the business, you had no expenses or income from it, there is no reason to do the worksheet other than that TT remembers you did one last year. So if you are in the part of the interview where it lists your businesses and has EDIT/DELETE to the right, delete the business from this years taxes and the useless schedule C will disappear with it.
