Previous year income on 1099-R and State Taxes

My wife filed for federal disability (not social security) in 2018. It was awarded in 2019 and received a lump sum payment to cover income from 2018 in late 2019. We received a CSA 1099-R. It deducted federal taxes but not state taxes because at the time we filed for disability we were living in a state that does not have state income tax. In mid 2018 we moved to a state that does have income tax. Turbotax wants to tax the whole amount at it shows as income in 2019 and we lived in the state with income tax for all of 2019. Is this the correct way to treat it and if not what do I need to do?
