"But If I trying to enter data from 1099-B - Turbo tax trying to get all
taxes again. I am pretty sure I doing something wrong and calculating
taxes twice, but can't find error."
Your error is that you are using the wrong basis when reporting the sale. Brokers need to only report the "out of pocket" cost when reporting trades of employer stock so if you simply enter the 1099-B as it reads you are reporting the income twice: once as compensation as reported on the W-2 and then again as "gain" as reported on the 1099-B.
Your per share basis in the stock is the same as the per share "fair market value" used by your employer to calculate the compensation created by the exercise. That's the per share basis you need to use to eliminate the "double income" reporting.
Enter the 1099-B exactly as it reads and then click the blue "I'll enter additional info on my own" button. On the next page enter the correct basis in the "Corrected cost basis" box. The correct basis is: (# of shares sold) x (per share basis for that lot.)
