Wow, this is a major flaw I just discovered on October 16th after I filed my taxes !
I did not detect because I saw the $3000 loss but I have a major loss loss carry forward from 2018 that did
not flow into 2019 automatically.
I wonder should I amend the form 1040X and re-do the Schedule D entries ? Or just correct to the 2018 known numbers when I do 2020 return in a few months time ?
