Did you use Turbo Tax for 2020? Then it should automatically carry over the Capital loss carryover.
The current year carryover loss from the prior year is on schedule D line 6 & 14.
On the income page The 2021 column shows the carryover to 2022) not your current loss for 2021). The 2020 column shows the carryover to 2021 not the loss for 2020.
And Schedule D doesn't actually show the carryover amount to next year. 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.
And if you have a negative AGI or negative taxable income it will show up on 1040 BUT it won't reduce the carryover to the next year.
