After I filed my 2021 taxes (and paid the amount due) I received an IRS letter advising me that that I was supposed to receive a 2021 stimulus check...which I had not. Thus far I have not taken any action on it since I do not believe I was due a payment.
I am still awaiting their notification that my return has been received. I sent it in on Feb 7th. Have had no luck getting in personal contact with anyone down there in Austin.
My guess is the “staff” decided to not come to work for months or years due to CCP virus.
