Well I can file an amendment through turbo tax because it keeps glitching, so I was going to use the form 1040x and mail it in, but I see nothing on that form or in instructions to correct a capital loss carryover.
In the screen shots you provided - when I do file my 2021 taxes (I haven’t started yet) I can included the carryover loss from 2019 as failing to provide on my 2020 tax return?
