After you file

I used the address in TurboTax 2021 for the mail out of my tax package which was Department of the Treasury, Internal Revenue Service, Austin, TX 73301.  I mailed the package by certified mail on 03-03-2022 and the documents show it was delivered, front desk/reception/mail room on 03-10-2022.  To date, I get NO response from the Govt IRS site that my refund is being processed or other.  All I get is an automated response from TurboTax regarding the matter.  Where do I go to find out where my tax return is, when will the refund be processed and when can I expect it?  Hope all don't suffer the same issues I'm having.  To date all I know is that my 2021 tax forms were delivered to Austin, TX from Phoenix, AZ.  But, I don't know if the tax submission or refund are being processed.  Thanks.
