When you first get into your return after saving and closing, go to the "Personal Info" / "You and Your Family" section right at the very beginning. You will first click on "Continue" which will bring you to the "Your Personal Info Summary" page. If you scroll down to the bottom, you should see a bold "Other State Income" title with an Edit button off to the far right. Click on "Edit" and it will bring you to a page where you can select "YES" - which will then open up a drop down menu for you to add a State.
