ISO sale income on W2, form 3921, turbo tax is double counting the income. How do I enter it so that it doesn't?

I have private company ISOs that I exercised and sold this year. The income is already in my W2 but the interview doesn't ask me that question. I don't have a 1099 for this, I got form 3921.

Add the amount in W2 to the cost basis in 1099B and enter the combined amount as the final adjusted cost basis in 1040. This way it won't be double counted.
