My job Corporate office is in GA but my home office where I work from is in AL but when I filed my taxes I filed on GA and AL and shouldn't have? How do I amend?

Here are the instructions - How to amend my state return(s)?   You should amend the GA return - none of your wages should be allocated to GA since you lived and worked all year in AL.   See Do I need to file a non resident return if I have an out of state employer?

If AL gave you a credit for taxes paid to another state (GA), you will need to amend your resident AL return as well.
