I moved from MD (income tax) to TX (no income tax). It appears as though TurboTax is applying the state income tax to the full calendar year. I moved in July. Solution?

The Maryland taxable income of a part year individual is calculated as if all income were earned in Maryland.  The Federal Adjusted Gross Income (AGI) will be adjusted using the Maryland adjustments to arrive at AGI from all sources. The AGI from all sources is used to determine the taxable income. After the taxable income is calculated, it is prorated using a percentage of the AGI from Maryland sources divided by the AGI from all sources. This prorated tax is the Maryland tax.
