In TurboTax in the My Info section you would select Florida as your resident state. Where asked if you lived in any other states you would select Yes, the state of Alabama and the date you moved to Florida. This assumes you did NOT work for an Alabama employer when you became a resident of Florida.
You will need to complete a part year resident Alabama state tax return reporting the income you earned while a resident of Alabama.
Florida does not have a state income tax so there is no Florida state income tax return to complete.
