I had the same problem and called in a support ticket. Also submitted a bug report. The support reply I received was to go to forms and basically fill out Schedule D where all the 1099-S information flows into.
I hope Intuit/TurboTax fixes this bug, it's a nuisance and more importantly there's other info I need to enter into Schedule D using the walk-me-thru guide so hopefully I won't encounter errors with that over-writing what I apparently need to enter manually (the 1099-S info).
The bug seems to be when the program asks "do you have a 1099-B" and you answer "no", it doesn't take you to the "type of investment sold" question, it basically asks you to fill out 1099-B information which is erroneous.
