How do I report the compensation income from an ISO sale if it’s not included on my W-2?

It is a disqualifying disposition and I have left the employer long ago so I don't get a W2 from the employer. For some reason, Turbotax online is not adding compensation income to "Other Income" on my Form 1040.
In online turbotax edition, I add "An employer without a W-2 on this return" in ISO option interview but still, I see no change in tax. I don't see any page where online edition is asking me whether the amount reported on you W-2.

 

Any help is highly appreciated.
