I'm running into the same issue. I have a W2 where box 16 lists both states. However, Turbotax does not correctly calculate the taxes owed to each state. For example, I have state A and state B. Turbotax assumes the taxes I need to pay to both states is my total income. This does not make any sense because it should be divided between them according to when I lived in each state. Any suggestions on how to fix this would be great!
