The 1099-B statement we get is also 326 pages long. The broker just allows a pdf download. I can't understand why turbotax doesn't allow pdf attachments like TaxAct does? See below is the page index of my 1099-B from broker. Page 2-309 are 1099-b transactions. Or are you suggesting we only mail Page 1 which is summary of form 1099-B?
