After you file

@ferrero1946 Are you asking about your 2019 return?   That you mailed in 2020?    Did you use a mailing service like certified mail so you could know for sure that the IRS received it?   Unless you did that, there is not a way to know if they got it.   Have you seen anything about your mailed return on the IRS site at any time--such as sometime between the time you mailed it and January of 2021?   By the time people began to file 2020 returns, any information about a 2019 return would not be showing any more on the IRS refund site.  They only show information for the most recent tax year.

 

To call the IRS:IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri

Listen to each menu before making the selection.

First choose your language. Press 1 for English.

Then do NOT choose the first choice re: "Refund", or it will send you to an automated phone line.

Instead, press 2 for "personal income tax".

Then press 1 for "form, tax history, or payment".  

Then press 3 "for all other questions."

Then press 2 "for all other questions."  It should then transfer you to an agent.
