The turbotax tool asked me to report the 3921 form in the year that I exercised the stock bu hold them, this year I sold some of stock options, then how to report the same 3921 form in this year's tax return? 1) should I have to input all shared listed in the 3921 form or just the sold share number? 2) since I already reported this same 3921 form in the previous year(cost basis adjusted), so should I use the adjusted cost basis in the 3921 form interview or still use what shows in the 3921? Thanks.
