Retirement tax questions

I filed my 2019 taxes LAST year in July and I STILL haven't gotten my refund nor can I even talk to anyone at the IRS or the IRS advocates office. So they are basically holding my money hostage. I had to mail in my return because of Turbo Tax system error so my filing sitting in a pile of unopened mail at the IRS offices. Since it wasn't processed I didn't get my stimulus check either. It's a HUGE CF. Don't expect them to help you. Don't expect anyone to help you. I depend on that money to pay bills and buy food... so It's off to the food banks I go. What a nightmare.
