Since you are residents of GA, then ALL your income is taxable by GA, regardless of where it was earned.
Florida has no income tax, so there is nothing to file there.
AL can tax you as a non-resident on income earned from work performed in AL. Since AL taxes were withheld on his W-2, you should file a non-resident AL tax return in addition to the GA return.
In TurboTax, be sure to complete the non-resident AL state return before you do your home state return, so that GA can credit you for the taxes paid to AL.
