You appear to be using Online TurboTax; at least that's what is indicated above underneath your question.
What is your situation in regard to the Federal return? Have you already filed the Federal return, or is it still in preparation and has not yet been filed? And if not yet filed, is the interview closed, and you need to know how to open it back up?
If you haven't yet actually filed the Federal return, but if TurboTax thinks you were finished, your return interview may be closed. If that's your situation, then here's how to open the unfiled return interview back up:
Click on the link "Add a State". That doesn't really add one, but will open the interview back up. Once the return interview is open, then you can make any edits to the unfiled Federal return.
NOTE: If you've already filed your Federal return, and if it's been accepted (if efiled), then don't use the above method. In that case report back on information on how to amend an already-filed return, if that's what you need.
