After you file

Ok ... since you used the TT non filer tool and it was accepted then you cannot refile it again ... that is why the IRS tool is rejecting the second filing.   Nothing you or anyone else can do but wait until the IRS processes the return you filed and issues you the stimulus payment.  Unfortunately the IRS staff as been cut to the bone due to the virus and are just now getting back into the office ... it will takes weeks for them to catch up with all the returns that have been stacking up so patience will be needed.  Check the IRS tool every couple of days to see your status ... also make sure you are entering the mailing address EXActLY as you have typed it on the form 1040 ... do not use the APT section.
