Capital Gains
I have entered my three capital gain amounts for 2021 - one is a short term gain and two are long term gains. These amounts are reflected on Schedule D. (short term on line 1b, long term on lines 8b and 9). In addition to these amounts that I have entered, a fourth amount appears on line 13 of Schedule D. I do not know where this fourth amount came from. I cannot find it in any of the worksheets for Schedule D. Can you please explain where the line 13 amount is drawn from?
