When entering the income from the 1099-DIV, should I enter the Payer or the Broker? It seems like either is acceptable. My combined 1099-DIV/Int/B lists the payer.

However, for the section where I enter the 1099-B information it looks like I need to enter the Broker, which makes me wonder if I should also be entering the Broker for the 1099-DIV information as well.

Also, silly question, but the IRS is not going to care about whether the full name of the broker is entered, will they? Wondering if I need to enter the "LLC" part of the broker name.
