Get your taxes done using TurboTax

Ok ... you failed to report the 1099-B from the broker on the return ... the basis for the stock you sold was reported on the W-2.  So it seems you only reported the W-2 and now the IRS needs the form 8949 & Sch D filled in as well.   Good news is that you will have a loss on the sale for the amount of the broker's sales fee.
