Look at your 2020 California Capital Loss Carryover Worksheet from 2020. The Carryover amount for 2021 will be on Part I, Line 8 (screenshot).

If so, this amount should flow to your CA return, where you may be asked to verify the California amount. 

Since we can't see your return in this forum, when you say your Carryover Loss is the same amount for 2019 and for 2020, does this mean that no part of your loss was used in 2020?

If so, the amount could be the same for 2021.
