Still not enough ... is the 2019 tax on one line only ? Or is it a combination of multiple lines ? Was this a year when you did not claim dependents ? Were there credits (or lack of them) involved ? Actually the 2019 year is the only one making sense right now.
I highly suggest you talk to someone in person locally as figuring this out on a forum is not the most effective method.
Don't know if TT support will be any help but you can try them ... contact details can be found here
