Of course the instructions for 1099-DIV preparers do instruct the broker to observes all the rules when it comes to what amounts can end up in the "Qualified Dividends" box of the 1099-DIV, and those rules have been in place for many years. Accordingly, I'd be surprised if you're seeing lots and lots of "classification" errors here.
What's the name of the broker issuing you the 1099-DIV? You may want to talk to them and determine if what you're reporting seeing "... these values are not accurate..." is, in fact, the case.
