I still never received my refund from 2019 though, so I’m thinking something was messed up with the filing. I sent everything by mail, so I’m hesitant to send 2...

Unfortunately it didn’t work. I may need my 2019 taxes fixed.

Putting in 0 didnt work either. Should I just redo the entire return? I don’t know how to go back and say I don’t have the 2019 return.
