I can share some information on this, @LAMAR685.

At this time there's no option to see the PIN in QuickBooks Desktop for security reasons. I suggest contacting the EFTPS support team so they'll be able to resend your PIN by U.S. Mail. The IRS can schedule a payment for you in the meantime if you verify certain information. For safety reasons, your PIN must be mailed and can't be given to you over the phone.

For additional information, you can click this article: Enroll in Electronic Federal Tax Payment System (EFTPS).

To see the detailed steps on how you can change your password in QuickBooks Desktop to match your new EFTPS Internet password, you can open this article: Update your EFTPS Internet password.
