You earned income from the same employer but lived part of the year in one state, then living in another state? If you moved to a new state during 2017, you'll normally file a part-year return for each state you lived in during 2017, assuming the state(s) collect income tax.
Please see the TurboTax FAQ on How do I file a part-year state return. https://ttlc.intuit.com/replies/3302008
