I do not think that is correct. Line 13 Schedule 1 is for capital gains only. Dividends are entered on lines 3a and 3b of 1040. Total income adds sum of Schedule 1 with lines 1 - 5 on the 1040. Including the dividends on Line 13 would result in doubling the dividend amount seeing that it is on Lines 3a and 3b of 1040.
