I agree, this is astonishingly difficult. I *know* I have to calculate AMT due to the exercise of ISO options, and the ability to locate where to indicate that is obtuse, and that is being generous. I have entered the AMT section, and nowhere is the phrase ISO to be found, other than in search results to pages such as this. There is an investment adjustment option, but nowhere to simply say I exercised X shares with a market value $Y dollars and an exercise price of $Z per share. Form 6251 points only to messages such as this in the help section. The information is not on the 1099-B, so I expect to enter it, but am so weary of looking where to do so that I am going to look at an alternative solution like H&R Block. Unbelievable.
