This is a question on Georgia Income Taxes.
The IRS allows you to payback Social Security and deduct the net payment (Amount paid back, less current years receipts) on line 28 of Itemized deductions. The Turbo tax program transfers itemized deductions to the state return including the payback.
Since social security was not taxable in Georgia when received is this correct? If not correct where are the regulations that specify this and where and how is it corrected on the return?

These are the Instructions for form 500 from Georgia.
LINES 12a-c Enter itemized deductions from Federal Schedule
A on Line 12a; enter adjustments for income taxes other than Georgia and investment interest expense for the production of
income exempt from Georgia tax on Line 12b. Subtract Line
12b from Line 12a; enter the total on Line 12c.
Leave Lines 11a-c blank if you itemize deductions.
When Federal itemized deductions are reduced because of
high income, the reduced amount should be used as the starting
point to compute Georgia itemized deductions.
If you itemize deductions on your Federal return, or if you are
married filing separate and your spouse itemizes deductions,
you must itemize deductions on your Georgia return. Include a copy of Federal Schedule A with your Georgia return.
