IRS Delays - More than 4 months since I filed my paper return

Hi All,

 

I filed a paper return in the month of November for the year 2020. I didn't hear anything about my refund until now. I am having a tough time getting hold of a live agent when I contacted the toll-free number. Is there a way I can get any status on my tax return? I tried looking up via the "where's my refund" app/tool, but it says there is nothing they could find based on the info I entered.  In all likelihood, IRS hasn't even opened my envelope.

 

Any information on how to know the status of my return would be helpful.
