I think the 0 in the 2019 column might be right.
On the income page The 2019 column shows the carryover to 2020 (not your current loss for 2019). Schedule D doesn't actually show the carryover amount. To find your Capital Loss Carryover amount you need to look at your return schedule D page 2. Line 16 will be your total loss and line 21 should be a max loss of 3,000. The difference between line 16 and 21 is the carryover loss for next year.
