Investors & landlords

I am confused by the taxation relating to RSU/PSU  stock. My company listed my stock on my W2 so I pay income tax on it when I receive it. Then according to TT I have to pay capital gains tax on the whole amount sincE ethe cost basis is $0. So this would mean I am being taxed twice! 

 

TT should ask for the adjusted cost basis not the cost basis surely.
