TurboTax Online pricing is for online preparation of your return, NOT e-filing (which is no extra charge). You will need to pay for both states to have TT Online prepare them, whether you e-file or not.
(You may want to consider MFJ or "separate on same return" for one or both states, especially if you both live in one of them. If you live in one state and work in another, unless a reciprocal agreement applies you will owe tax to BOTH states, though your resident state will probably credit you for what you pay the other state. Though the MFS "penalty" isn't as bad in most states as on Federal returns, you still may benefit by filing jointly.)
