Sorry you bought the wrong one. It doesn't work that way. Turbo Tax doesn't price match the stores.
To buy a state program directly from TurboTax in Basic or Deluxe Federal only is $45 now. It was $40 until March 1 then the early prices expired. Maybe you can go back to where you bought it and get the one with state. Why didn't they have it? Where did you buy it?
See the Desktop prices here. Deluxe with state is now $80. And a second different state is $45. So you will end up spending 40+45=85 just $5 more. Maybe they will give you the difference?
