I got the transcript and found the amount!
it actually says:
Refund issued 12-24-2020 $xxxx
776 Interest credited to your account 01-04-2021 -$yyy
740 Undelivered refund returned to IRS 01-04-2021 -$xxxx
777 Reduced or removed interest 01-04-2021 $yyy
credited to your account
Now the problem becomes contacting the IRS to have the check sent again...
