Regarding paper returns filed for 2020.

I have filed two paper returns via certified mail before the due date and the IRS has not acknowledged the existence of either tax return.  They cannot be found in the system.  The certified return receipt was received about 12 weeks later, unsigned and not dated by the IRS of course.

when you are an ERO with an EFIN but you use your SS# instead of applying for a company tax id #, you still cannot file your personal taxes, which is insane to me.  I can file 60 tax returns for everyone else, but not for myself.  Where is the logic behind it?
