This information should be available in the Deductions & Credits section where it asks if you made contributions to a qualified retirement plan. I've been wondering how TurboTax calculated a credit in this area when I never entered any retirement contributions, and my W2 doesn't list any contribution amount that coincides with the Box 13 checkmark. I've been searching for this answer for 20 minutes and finally found it here. There is no info button available on those screens to help answer this question.
