Generally I don't advise using the "guided" interviews for reporting the sale of stock acquired via some sort of employee stock incentive program, with the exception of stock acquired via an ESPP. There's nothing straight forward about entering the sale of stock acquired in this fashion because any sale of this stock can create compensation income, that needs to be reported, and this compensation income is added to your original purchase price in determining gain or loss, and this guided interview handles all this correctly.
So, use the "ESPP" guided interview. However, you may (probably will) find that you don't have all the information required to report these sales absolutely correctly. In that case you might have to resort to "best guess" estimates.
