I had to file my 2020 return late via mail. I mail it to the IRS in October 2021. They never received it or did nothing with it. I mailed it again Feb 2022 with delivery confirmation. I can't get ahold of anyone at the IRS. I have wrote letters with no response. It will be a tax refund. What can I do? Who can I call? Do I file my 2021 taxes?
