I figured it out for my case.
What I found out is that my company's RSU management company distributes 1099-B with cost basis NOT reported to IRS, as a result you have to go through the pain and figure out all the cost basis one by one, how many rsu you got, how many you sold for how much and also don't forget that cost basis for you was likey not 0 ( despite turbotax suggesting - often 0) , as it is typically already in your paycheck and taxed. After you do this it will calculate correctly and tt will no longer complain.
