Status update on 2018 Amended Return

Hi,

 

on 04/17/2020 I filed a 1040X, and after that, I lost track of it (the tool was not working properly).

Now, going back to the IRS tool, great news: on 01/15/2021 has been "completed", and the description says the following:

 

"We processed your amended return on January 15, 2021. The adjustment on your account resulted in a refund. You should have received your refund and/or a notice if your refund was adjusted to cover past due obligations."

 

From what I'm understanding, has been figured that they owed me the refund, but I never received neither a letter nor a refund.

 

Does something like that never happened to you? How can I understand what's happening here?

Thanks
