I have not recieved any of the stimulus payments ? tried contacting IRS through phone and on line and both was a ***** end. just filed my 2020 taxes

If you just filed your 2020 tax return, did you use the recovery rebate credit section so that you could indicate that you did not receive the stimulus checks?   Look at your Form 1040.   Is there an amount on line 30?    If there is an amount there, that is your stimulus money that is going to be included in your refund.    If the line is blank then you are going to have to wait for the IRS to fully process the return you just filed and then amend so that you can use the recovery rebate credit to get the EIP payments.

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

The first 2 missing stimulus payments are included on the 2020 return line 30  and when the 2020 return has been processed it will trigger the release of the third stimulus payment so all you can do now is wait for the processing to happen.
