That's the Georgia Individual State Income Tax Return form. Did you file a tax return with the state? If so, just provide them a copy of said tax return. I would assume that if you e-filed your state taxes with Turbotax, that you printed a hard copy of it for your records in case the state ever comes back asking you to prove that you did "in fact" file a tax return for whatever year may be in question.
If you did not file a tax return with the state of Georgia, then obviously you can not provide them that which does not exist.
