After fixing a data entry mistake or two, I was able to make them come out same. However, I was much happier with TurboTax's handling of employee stock options, because it walks you through how to correct the incorrect cost basis that brokerages are required to report by law. (This changed a few years ago.)

At that point I could have submitted either one, but ended up paying for TurboTax since I felt like rewarding them for better UI.

(While fixing an error, I did run into a recalculation bug in TurboTax, though; it's not clear how to report it.)
