Filing by mail without IP PIN due to e-file rejection

My e-file was rejected due to not having the IP PIN. However this year they did not send anything.  I have tried to call but due to the pandemic, they are closed. I attempted to retrieve the IP Pin using the IRS website. However, they have specific requirements. I do not meet those. On the Turbo Tax site it says, I would still need to place my 6-digit IP PIN number if I chose to send by mail.  The reject code was specific to this IP Pin number that I need to have in order to file. My question is how do I go about filing by mail, without this specific PIN?  Seems I can not do much at this juncture.  What can I do?
