Where is my tax refund for last year? I was told it would be deposit in my bank account by March 21, 2022.

I am a retired government employee.   I was told that you completed my taxes for the last tax yeae and my refund will be deposited by  February 21, 2022.  Please tell what I need to do to receive my refund.
I misspoke about the date you gave me for deposit inti my account, it was Feb. 21.
Please I am in need of the refund.  
I have received a second notice from the Federal Government about my 2019 taxes.  Please help.
