I filed my tax for 2019 in paper last year but I still have not received a refund. I can't get any information/update through where is my refund tool as well. I know that there has been delays processing mailed in returns at IRS but I am just wondering is such a delay now normal?
Also, Can I file my tax for 2020 given that IRS has not processed my 2019 tax return?
Thank you.
