I am having this same error. I cannot e-file my S-Corp return to Georgia. I was able to e-file my federal return. Does anyone have a solution to this? TT support sent me to a website that lists Georgia form availability. Some necessary forms were not supported, and others like 600S would be available 3/15/24. When I spoke with Georgia DOR support, they knew of no reason why e-filing would be an issue. They said it had to be a software (i.e., TT) issue.
