I used to have a managed brokerage account, and I just received my 1099 composite forms which include 1099-DIV, INT and 1099-B forms. Do I need to file any of this? I am specifically puzzled by the 1099-B as this has some information in it.

I no longer have this account but I image since I did have one last year I need to file some of these forms? Can anyone confirm?

You have to file all those forms or get a nasty letter from the IRS.
