I believe if you e-file you will need to attach copies of all your W2Gs.
I file using TaxCut but since we have so many W2Gs, I print out my return
and total the number of W2Gs and any other winnings as "gambling income",
then itemize and put in "gambling losses". I attach a separate list that
shows the daily totals of all W2Gs/wins and all losses. This isn't necessary,
but I usually attach it as well.
