If you want to itemize deductions on the Georgia state return you must also itemize deductions on your federal return. If TurboTax is recommending the standard deduction and you want to claim your itemized deductions, you can switch to itemized deductions.
Follow the directions in the TurboTax FAQ below if you wish to switch to itemized deductions on your federal return so that you can claim them on your Georgia return.
