" The key to avoiding double taxation is to add the ordinary income shown on your W-2 for the shares vesting to your basis for the subsequent sale. "
Add where? As soon as I entered by 1099-B, the double taxation showed up. I tried to use the "I need to adjust my total cost basis", but then it wanted an adjustment code. None of those seemed to indicate "already reported on W-2". The referenced ISO page talked about Schedule D. Great. That makes sense, but my TurboTax didn't prepare a schedule D for me.
