If my returns were rejected without an IP PIN and I tried getting a IRS code to fix it but my phone didn’t accept it, will I be penalized for being late with my return?

I already tried to set up an IRS account and a text message with a code from the IRS was attempted to be sent, but my non-smart phone (with texting abilities) couldn't receive the text.  So now I've been told via messages that I must now wait for the code in the usps mail.  I will be late filing now and don't know what else to do
