2021 and 2022 tax forms didn't show the correct carryover capital loss. How to fix this?

Hi, I found that my 2021 and 2022 tax forms didn't show the correct carryover capital loss. Wondering how to fix this so that it is taken into account for my 2023 tax return? Thank you!

How do you know? Did you use an app to prepare the returns? if they are wrong then you'll need to file amended returns so the correct carryover to the next year is shown. failure could cause disallowance.
