@Fiddle Well, you just showed me a new fact on the 1099-R that I was not aware of, Thank You.
I removed the check mark on the IRA/SEP/SIMPLE box and sure enough, it doubled the amount of the taxable distribution in box 2a on the Form 1099-R that flowed to Georgia Schedule 1 Retirement Income Exclusion Line 11. The amount should be $2,500 but is doubled to $5,000.
So this is a bug in the TurboTax Georgia state program. I will notify the TurboTax Moderators of this forum who will pass this on to the developers. There is no telling when this will be corrected.
Thanks again for posting this problem and updating my on the Roth IRA issue.
