Line 13 of Schedule 1 includes all capital gains included in the return. If you received a 1099-DIV, for example, that was reporting a capital gain distribution, that amount would be included on Schedule 1, line 13 in addition to any capital gain calculated on Schedule D.
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.
Capital Gains can also come from 1099Div box 2a and any K-1 you received.
VolvoGirl - no, that is not correct. 1099-DIV box 2a is the sum of ordinary and qualified dividends. Those two amounts are already entered on lines 3 and 3b of 1040. Please see comment above for explanation
I also did not receive any k-1 income. Additionally, even if the Schedule 1 Line 13 added dividends to capital gains, adding my actual dividends to my actual capital gains results in a different much lower number.
I don't know what 1099Div you are looking at but box 1b Is the part (or all) of box 1a that is qualified. Box 2a is a totally separate amount and not part of 1a or 1b and NOT the total.
