On my state return, what is Georgia interest adjustments?

If you had non-taxable interest from municipal or state bonds on your federal tax return, you have to add back (adjust) to your Georgia Income any portion of that interest that was not from Georgia State or Municipal bonds. 

I am a nonresident of Georgia but have passive income from an LLC in Georgia.  Do I have to add back (adjust) municipal bond interest from states outside Georgia?  Or is this required only of residents?
