Understand, too, that TurboTax is not going to handle those issues unless you take the right path in the "Stocks, Mutual Funds, Bonds, Other" interview. Be sure that you use the "Guide me" process here and tell TurboTax that the stock sold was acquired via an ISO. That's what will make TurboTax enter a "reversing" entry for the sale over on Form 6521 and the AMT version of Schedule D.
