Deductions & credits

gross dividends on line 1a of 1099 need to be entered and also the portion that's qualified on line 1b.

1b can't be greater than 1a. on Turbotax 1099-div there's a section below line 12 to adjust dividends.

on the 1040 itself, total dividends appear on line 3b while qualified dividends appear on line 3a and that should be the $7800 unless there is something in the adjustment section of the 1099-DIV.
