My 1099-DIV has no totals, just numerous lines from each fund. Last year I added the lines together for the totals to report in boxes (1a), (1b), and (1c). Help!

I am no expert, but adding up all the lines for each fund and entering the sum in the boxes is the way I would do it.  You can double click on a box and add up your lines in the pop-up window.
