It's not really clear what you are referring to when you say "the sales info section i.e. stock, bond, mutual or other?" Presumably you have a 1099-B with all the necessary information you need printed on it and unless you dip down into the "guided" interviews, which you don't need to do, TurboTax doesn't ask that question.
The 1099-B interview page has a box labeled "Description" and, presumably, the 1099-B has that information. I'd think it would be along the lines of "Bank of XYZ 12-Month CD" or some such.
