Deluxe desktop version (CD/download) can prepare a Schedule D, but online Deluxe cannot.
The desktop version of Deluxe can handle all the usual Federal forms. Online Deluxe, however, cannot prepare Sched. C,D,E,F, or enter K-1 info.
Be aware that desktop Deluxe comes in 2 versions--one that is Federal only and one that is combo Federal and State. When purchased from TurboTax, it is the combo Fed and State version. If purchased elsewhere, you have to be careful about which Deluxe you are buying.
