In Box 15. I live in 1 state and work in another. I had income tax taken out for both states. 1 page has TOTAL STATE, 1 has the state of employment

Probably. Let me give 2 examples to answer your question. The state wages section can be changed to indicate your reality but keep the state tax paid the same.

All wages earned out of state:

State A $XX

State B $XX

Some wages earned out of state:

State C $YY

State D $ZZ

If your w2 looks like the top example, you only need to enter the out of state wages and taxes paid. The program will automatically carry all income to your resident state. Since you paid state tax, you can enter the full amount along with the tax paid. 

If your w2 looks like the second example, then you want the total for state C and state D to add up to your total income since the program will carry the out of state income to your state.

For most states, you will fill out the non-resident return first to calculate a tax liability and then do your resident return. If the states have a reciprocal agreement, you may not need to file the nonresident return. See Which states have reciprocal agreements? - TurboTax Support

There are reverse credit states and the NE states have a new agreement. If you want to reply with the states involved, we can help.
