Tax refund status

I didn’t file my 2020 taxes until January 2022.  The IRS required me to complete an authentication process and that was completed August 2022.  When I check my refund station it has shown “Pending” since August of last year.  I am not making any progress on the status online or by calling the number.  The chat is closed.  I have tried to find an address to mail an inquiry but no luck there either.  

 

I would at least like to verify that they are not waiting on me for anything.   Any advice?
