After you file

I haven’t received anything! And I tried calling a million numbers but every IRS office is closed down due to the pandemic. So I just keep getting automated messages. I am just trying to understand why there is such a huge delay considering I have gotten my state refund weeks ago already. And there is nothing on the IRS website saying when I could expect to receive the other refund. 
And thank you so much for your response! You are the first person all day I have been able to get any type of help from so I really appreciate you taking your time to read my problem.
