I am filling out 1099-DIV. If there was only a distribution of $1547 qualified dividends and no other dividends were distributed, should I also fill out $1547 for box 1a. Total ordinary dividends? Or do I only need to fill out 1b? I get a warning if the amount in box 1a is less than the amount in 1b, but I also see that the software calculator totals both amounts if I fill in both boxes.
