DH has used TurboTax for several years now--we are both retired now,but also used when we had kids at home (so about 15yrs)and we both have income from other sources (DH as a writer, me with quilting). Our grown kids also use TurboTax and son has same situation you are talking about (work in one state, live in another) plus has a city earnings tax to deal with and TurboTax figures it all out for him.
