I have over 5000 trades in 2006. On my 1099-B I got a total sales proceeds, but then there is a "SUPPLEMENTAL TAX INFORMATION" which lists all buy transactions. Using these information it shows a profit that's more than three times what I actually made! I'm a day trader and there is no mark to market issue. Should I ignore the 100 pages of SUPPLEMENTAL TAX INFORMATION and enter the information from my own record? Will this huge discrepancy be a certain cause for an audit?
