Is there a BUG i nthe AMT interview? (Desktop verions)

[TomYoung]

I see that TurboTax has completely changed the AMT interview this year.  I used the new interview in an attempt to make the needed adjustment for the sale of stock acquired via an ISO, held through the year end and then later sold in a Qualifying Disposition.  

The interview now asks you if  "I need to make an AMT adjustment to my investment income or expenses" and I ticked that box.  The page that comes up in response asks for adjustments needed to Gross investment income, Net gain from disposing of investment property and Net capital gain from disposing of investment property.

What I found was that no matter what numbers I entered in those boxes, no matter how large or with what sign, none of these numbers showed up anywhere in the income tax return.   Not on Form 6251, not on the Alternative Minimum Tax Worksheet, not on the Schedule D AMT form.  Nowhere.
