Search your local IRS phone number and call that number. Don't bother calling the main line - the lines are too busy and you'll get told to call back another day.
I called my local office and spoke to someone - Yay! The person I spoke to was very helpful. She was able to find my application which I mailed on 4/26/20.
Apparently it was processed on 11/25/20 and didn't post correctly due to some error. The error was fixed (fingers crossed!) and hopefully I will see a refund in 6-8 weeks.
