Because your wife earned money in two states, you will need to file two state returns this year.
In the Personal Information section of TurboTax there will be a question about earning money in another state. Her answer to that question will be yes and she will enter GA. It is important to do that so TurboTax knows which state to prepare first.
Federal law forbids double taxation by states. What happens is that you indicate for each state how much of the income was made in that state. The questions in TurboTax will guide you on how to enter the income allocation for the residential and non-residential state.
