The form represents multiple share sales but only allows a single date to be entered so we fill in dates that match the type of gain (e.g. short-term or long-term). You may also see the dates reported as "Various" from other payers. The supplemental table shows the details for all of the trades.
How were the sale dates determined on the 1099-B?
