If you're going to mail it in, forget about getting a stimulus check, PPU, or unemployment. The IRS has been out for weeks and won't be back for several more.
If you mail your return in it won't be seen for months, then they're going to deny it because there's no IP Pin on your paper file. You'll then have to go through an additional identity verification process. This is right off the IRS website.
If you need help now, and can't access your IP PIN, forget about ever getting financial help. By the time the IRS gets back, the window to apply will be closed.
