My problem is that the Brokerage that received the company stock only has an entry for the Gross Proceeds.All the other entries have $0.00

I have there cost basis for when it was transferred from my 401k to the Brokerage, which was just a few months before I sold about 1/2 of the stock.Is this the ...

So where is the the user of TT supposed to enter the information?The 1099-B form that I received only has an entry for the total proceeds
