How much are your current 2020 gains? If you didn't have any losses then the whole 2696 is used up on your 2020 return. Check 1040 line 7.
You get to first offset the loss against any gains you have each year so that can use more of it up. Then after applying the loss to the current gains you can take a max loss of 3,000 (1,500 MFS)per year. Turbo Tax does all the calculations for you. Just enter the prior year carryover amount.
On the income page The 2020 column shows the carryover to 2021 (not your current loss for 2020). 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.
