To add to my question:
The stock option gain was reported on W2.
I also received 1099B, if I entered the total proceed and total cost, this income will be double taxed.
So how do I adjust the total cost in Turbo Tax?
Do I need the W2 amount to the Total Cost Base or do I click "I need to enter amounts from box 1f, box 1g, or other adjustments, and enter total adjustments to gain or (loss) with - W2 amount?
