I called in and spoke to a TurboTax CPA. He couldn't find any reason for the GA Schedule 1 adjustment. Basically he told me to enter a "Subtraction to Income" on Schedule 1 to wash out the addition.
In response to the other post.....This has nothing to do with State Income Tax on Schedule A. I've itemized for years and there has never been a "Federal Schedule A Adjustment" appear on GA Schedule 1.
The amount for me also equals 2.5% of my AGI. BUT, it has nothing to do with medical expenses. If GA allowed 10% instead of 7.5%, the deduction would be bigger and there would be a SUBTRACTION to income. Besides, as someone else posted, it is 7.5% for 2019. The 10% begins this year.
I think there is a glitch in TurboTax as it relates to itemizing deductions. It also happened on my mom's return.
