which 1099B form do I send to the IRS, the one with all the sale dates and gain or loss dates or the one with just the totals for this tax year?

It depends. If you are required to attach your 1099-B you should include the one with all the sale dates and gain/loss dates.

What is the Box Category you are reporting? see exception below.

If you are not excused by the detail reporting exception,
IRS requires details of your SELL transactions to be supplied on some Form 8949,
or on your other forms (e.g. consolidated 1099-B or spreadsheet) which have the same information and in the same manner as Form 8949.

This is so, even when the broker has sent details to the IRS already.

Detail Reporting Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary. No attachment is necessary.

The exception does not include wash sales, since they have an adjustment.
