I'm getting audited for 2008 and need to file an ammended Schedule D. The examiner wants me to tie back to the trades listed on my 1099 from my broker - but I was trading a little longer term and essentially trading around a core position so there aren't clean buy/sell lots. For example, scale into a position over a few weeks... sell a few hundred shares at highs and add a few hundred shares on the dips. I have no idea how to assign a basis for the positions. Can I just attach a spreadsheet? Unfortunatley my broker does not have an "export to excel" function prior to year 2009... so I'm SOL and stuck manually doing this. Thx for any help!
