On our broker 1099, they now report the basis to the IRS.  I am having a hard time making my proceeds and cost basis match the 1099 report.  I also have a number of items mark with a wash sale adjustment.  The problem is that all of these stocks were ones that we sold all of the shares but there was dividend reinvestment that happen within 90 days of the sale.  Some of the wash sales adjustment appear in the long term transactions. We did not buy any more shares after the total sale.  Shouldn’t I be able to claim those loses?  Since I no longer hold those shares.

Would eliminating dividend reinvestment simplified the lots reporting?
