You might have to call them and ask about that .
I seem to recall that under the old system, Vanguard did create separate -DIV forms for each of their mutual funds, when holding separate mutual funds. thus, 5 mutual funds in the old account would have 5x1099-DIV forms. (but I'm not a Vanguard Customer)
But once they convert to a brokerage...then it is certainly possible there is just one 1099-DIV (and details in a Supplemental Worksheet on their PDF forms that are created separately), since it can be handled all as one for tax reporting. That's the way my Fidelity brokerage works....I several Mutual Funds, and stocks an such...all just goes as one total on the year-end 1099-DIV. No extra paperwork.
Ask Vanguard....or maybe another vanguard customer with more info will notice this.
