If you worked in one state and lived
in another, you will need to file a Non-resident return for
the state where you worked and a Resident return for the state where
you live. Some states, e.g. Florida, Nevada, Texas, Washington,
do not have a state tax, in which case you will only file a return for the
state that has a tax.
Don't worry - you'll only pay taxes on your state earnings to
one state. Your Resident state must offer you
a credit for the taxes you pay to other states.
Remember to let TurboTax know you worked in other states
- edit "My Info" in your Federal online
return - and to complete your Non-resident return before beginning
your Resident return, in order to properly calculate the credit your home state
owes you.
