Need status info on mailed in returns (fed and State)

When trying to e-file my returns, I kept getting rejected messages ---   after several tries, and working with several of your experts, I finally found the problem  -- my wife had passed and I would have to file by mail.

That was done 3-13-2020.  To this date, I have no notice that returns have been received.  Is there something, I need to do ? Where can I look for an answer ...
