Get your taxes done using TurboTax

There is only one address on your federal tax return. That address is simply a mailing address, and doesn't mean much beyond that. The IRS doesn't care what state you live in, or what state your spouse lives in. If you prefer to file a joint federal return, just pick the address of the one who would prefer to receive any possible mail from the IRS.

Every state is different. In some states, you can file a joint return with your nonresident spouse, and in others you cannot. Moreover, in some states you may prefer to file separately for state purposes.

If you can or want to file separate state returns, it is sometimes easier to do so with an additional username in Turbo Tax. With that username, you prepare a "pretend" separate federal return based on your individual data, and then transmit the separate state return on its own.  

Obviously, that part of the question cannot be addressed specifically without knowing the states in question.
