How do I calculate the Depreciation Adjustment Addition for Georgia return? I expected TurboTax to do this.

TurboTax dose not compute that adjustment. 

HERE is a link of the depreciation adjustment the federal may allowed that the Georgia return does not. 

The most likely adjustment would be if you claimed any Bonus/Special Depreciation. Georgia does not recognize that and the depreciation would need to be added back to income for that. 

In following years, depreciation for that asset might need to be subtracted from income on the Georgia return if the asset has no basis left on your federal return, (therefore no further depreciation taken)

Georgia does recognize the Section 179 Deduction, so no adjustment needs to be made for that.
