Georgia "Income and Retirement Worksheets" State Review error

An error occurs during the Georgia State Review at the "Income and Retirement Worksheets" form. On this form under "Income" line 7D says, "Other Subtraction #7 withdrawals with GA/Fed tax difference" the State Review ends and asks one to enter a number.

Shouldn't TurboTax fill in this information automatically by asking the needed question or getting this information from already asked questions?

I do not know what is being asked by line 7D so I do not know what to manually enter.

 

Thanks for the help.
