There is more than one approach here. However, of paramount importance is that your Sch D totals agree with the gross proceeds reported on your 1099-B; expect a letter from the IRS requesting an explanation if they don't.
Some traders make copies of the monthly statements (which show all trading activity) they receive from their brokers and attach them to their returns. Others don't bother attaching the statements but merely report the trades (all short term) as "various" and enter the gross amounts in the appropriate columns. Yet another approach is to show each and every trade on Sch D, using reams of D1s. The last is probably the most technically correct but, IMHO, is a waste of paper and I sincerely doubt the IRS really appreciates that. I think they'd prefer your totals match the numbers on the 1099s than anything else.
