I have not heard from the IRS about my 2018 tax return. On the irs.gov site under my account, it says that "your 2018 Tax Return has not been processed due date passed.

When did you mail in the 2018 return ?  

10/15/2019 with USPS, but with no tracking. Have the receipt thought. Trying to call IRS but still not getting through, trying daily.
