Where do I enter contributions for a Georgia 529 account?

[Hal_Al]

There is no federal deduction for making a contribution to a 529 plan. Some states allow a deduction on the state return. If your state is one, it will come up in the state interview  (in GA, only the Path2College 529 Plan qualifies); usually in the "Here's how (your state) handles income differently" section. For a list, see:

The tax break comes in the future, when you take the money out to pay for education.  All earnings (interest, dividends and capital gains) over the years is tax free if the distribution is used to pay for education, including room & board.
