After you file

I saw the help video on how to amend, but I already updated my return in TurboTax Deluxe 2017. I had to have a company modify a 1099 they  sent me so I went in and changed my schedule C in turbotax, thinking it would just re-file for me. I got to the end and it wouldn't do that for my federal/state. So I guess I have to file an amended return, but I already made the changes in my return in TurboTax, so how can I amend with the new info?
