I have always been able to record and receive credit for my 529 contributions in prior years using Turbo Tax. This year I do not see where I can do that. Please help.

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; usually in the "Here's how (your state) handles income differently" section.

If you can't find it, identify your state for more specific help.
