The settlement should be in box 3, not box 7. If in box 7, it is harder to get the program to accept it as "other" income. There should be a series of testing questions like "is this similar to your regular job", "did you intend to earn a profit" and so on. You need to answer those questions as far away from the idea of work as possible (mostly answering no.) If the money was in box 3 but you indicated it was wages, that might have created a blank schedule C.
Try deleting the 1099-MISC from the income page (there should be a trash can icon) then go to the bottom right where it says something like My Account; click that link and run through the options until you get to "Remove a form." (They've changed the wording, I don't know exactly where it is this year.) Remove schedule C. Log out, log back in, and enter the 1099-MISC again making sure to pick the choices that will have it show up as other income instead of self-employment.
Also, check your version of Turbotax, if using Turbotax online, you might have been bumped up into the Self-Employment version. If you want to get back to the cheaper Deluxe version, you need to "clear and start over" which will do exactly that, start you over from scratch in the deluxe version, that should also clear the 1099 and schedule C (along with everything else.)
