Deductions & credits

Look at your closing documents including the HUD-1.  The state of Georgia does not have any type of tax on the sale of a personal residence.
Your gain on the sale of a personal residence is the Sales Price minus the Adjusted Basis (Purchase price plus the cost of improvements) minus the sales expenses.
Where on the HUD-1 is this 3% shown?  How did the attorney arrive at  the $79,000 gain?  Have you got an explanation from the attorney?
