Thanks for responding. I found this reply on another thread but I can't get to it because I must have bypassed the interview already: "
The correct place to enter a cost basis adjustment is on a different screen than the one you are using.
In the "Tell us about your Box __ sales from your 1099-B" screen, you need to check "This sale involves an employee stock plan (including ESPP) or another uncommon situation."
The next two screens will allow you to enter the correct adjusted cost basis (not an adjustment to the reported basis)."
