Can I change the dollar amount on form 1099-DIV for line 1b (qualified dividends) based on supplemental information I received?

Vanguard sent me supplemental information saying that "100% of the short-term capital gains distributions of certain funds are qualified short-term capital gains distributions (QSGs)". A municipal bond fund of mine is one of those funds.
The short-term capital gain distribution is not included in line 1b (qualified dividends), only on line 1a (total ordinary dividends).     
Am I able to change the number in line 1b to reflect this supplemental information? What concerns me is this will be different from the Form 1099-DIV that the IRS receives, with no explanation.
