You do not have to attach them, just have then if they audit(My first HP someone saved Dog Race slips and Lotto tickets, I had a whole shoe box)...I think most people just total wins and losses from all properties and come out with a final number. Some people say that's not right but I think that's how most do it......The last part I would have to ask my wife, we always do the long form so it's not a problem but you could be right on that last part.....
