Retirement tax questions

Hi, 

I have AA and D in block 12 of W-2 with amounts and am completing the deductions and credit section of the Turbo Tax and need advise as to wether I have to list these totals as Traditional and Roth contributions or is it taken care of in the W-2 section?  I think this (deductions and credits section/Traditional and Roth contributions) applies to non-TSP IRA that i am sure does get listed in that section. Please clarify.
