If you've filed you can file an amended return. If you are referring to the turbotax online process I can not say. If you downloaded TurboTax and are in the process of answering questions you can always select the areas to revise from a list across the top of the screen just below the red check mark, starting with personal info, federal taxes, state, etc. When you select one of them sub categories appear for sub categories. Good luck!
