I entered Form 3291 from "ISO Exercise and Hold" interview, and entered 550 in "Number of Shares Transferred (Box 5)". Since I actually sold 50 of 550 ISO in the same day, so I entered that 50 ISO from "Stocks, Mutual Funds, Bonds, Other" interview. Then after going through "Alternative Minimum Tax (AMT)"interview from "Other Tax Situation", when I clicked "show more" for my "Alternative Minimum Tax" it still showed the total dollars for 550 ISO in "Incentive stock options" line, which made the "Alternative Minimum Taxable Income" higher than expected. Turbotax didn't disqualify disposition the 50 sold ISO from the 550 exercised ISO, do you know why? or should I enter 500 in "Number of Shares Transferred (Box 5) " from "ISO Exercise and Hold" interview, even it's not what Form 3291 says?
