If you did not take affirmative action to make AL your domcile state then MN was still your tax resident state all year and AL was non-resident/transitory. For example, did you register to vote in AL and/or change your driver's license to AL and/or buy a home in AL? If the answer is "No" then AL was not your resident state at all since you did not live there at least 7 months.
In this case you will file non-resident AL for the income earned while living there. You would also file non-resident GA for the income earned while working in GA. Take note of the income taxed and the income tax imposed by the non-resident states. Those numbers will be used to claim a credit on your MN resident return for taxes paid to another state to mitigate the double taxation since MN will tax all income from all sources.
If, however, you did take affirmative action to change your domcile to AL then you would claim part-year residence in AL for Jan-Mar and MN will be your resident state beginning 1 Apr 2021. In TurboTax it is not the date that matters but the time in each state. So three months in AL and nine in MN ending on 31 Dec.
