Exempt-interest dividends added to Ordinary Div?

My 1099-DIV shows $X in Box 1a for Total Ordinary Dividends and $Y in Box 12 for Exempt-Interest Dividends. On the Turbo Tax Deductions & Credits screen, the total Dividends on 1099-DIV equals Box 1a + Box 12 ($X + $Y). Is this correct? Shouldn't the exempt dividends be subtracted from the total dividends? When I further open the screen for that line item in Turbo Tax the entries match my 1099 Boxes 2a (Cap Gains Dist), 12 (Exempt Div), and 1a (Ord Div).
