I assume you live in Georgia and that you are filing a resident GA return. If so, Georgia will want a copy of your AL return attached to it to confirm that you should have a credit in GA for AL taxes paid.
If you itemized on your federal return, GA also wants a copy of just your federal Schedule A 1040 (your itemized deductions). If you used the standard deduction on your federal return then you do not need to attach Schedule A.
Attach a copy of pages one and two of your 1040 (page 1 has your address, etc and page 2 shows your final federal tax).
If you have any forms such as 1099s that have Georgia tax withheld, you should attach the a copy of the forms with Georgia tax withholding to your GA return.
You do not need to attach a copy of your W-2.
