Moved from state w income tax to state wo in 2017. Employer continued to withhold state tax until April 2018. State return won't accept 0% allocation of 2018 wages.

I am trying to get the 2018 state tax withheld by my employer in a state with an income tax (where I lived partially in 2017) refunded but Turbotax will not allow me to allocate 0% of 2018 wages to the state (because my federal return indicates I paid state tax in that state). I've tried selecting non-resident, partial resident (but this doesn't make sense as it asks for a move date and I didn't move there or from there in 2018), tried to allocate 0 days, 0% of wages to the state. Nothing works and Turbotax continues to calculate what I would "owe" if I earned my entire 2018 income in the taxed state. What should I do? I should be able to receive the refund in full as I didn't live there at all.
