Yes, you can choose to file only one state using TurboTax even if you need to file two states.
Just be aware that depending on the reason you need to file the second state that you may need information from the state return not done in TurboTax to accurately complete the one that is done with TurboTax if you are claiming a credit for taxes paid to another state.
