I'm not at all sure what additional help is available, in general, for stocks, bonds, royalties and mutual funds. All the desktop versions support the same Forms and Schedules so, in theory, any sale of any product can be recorded using the cheapest desktop product. However, I am aware that the "Deluxe" product does not have step-by-step "interviews" to help you record the sale of stock acquired via the various employer stock incentive programs - RSU's, ISO's, ESPP's and the like - where the Premier version does.
