You should be able to do that using the "Stocks, Mutual Funds, Bonds, Other" interview.
If you didn't get a 1099-B then you should be dropped right into an interview where you select "Stock" as what was sold. As you proceed with the interview at some point you'll come to a page that asks about "Special situations" and that's where you'll indicate SBS.
If you did get a 1099-B then get into that same interview flow by clicking on "Guide me step by step".
