2023 Georgia Schedule 3 Line 8A is red

Help! The red field is preventing e-filing of the Georgia state return. A few individuals at TurboTax advised overriding the calculated field with the total from line 8B + line 8C, which removes the red flag but number remains red. An attempt to e-file was prevented due to having an overridden field.

Does anyone know the data source for "Federal Income after Georgia Adjustment" line 4?

I was able to replicate the same problem with a newly created Georgia state return.

I have completed Schedule 3 for the past two years and never had to deal with this issue before.
