I share that users frustration, and the person who responded did not answer it at all!  I have the same problem, cant re-apply, I don't know where to find my PIN from last year, QB sends me to IRS and EFTPS, I have called, been on hold for hours, and everyone sends me back to Quick Books, even the IRS says you can't request anything except through the software you are using and their form, cant request from IRS directly!   This is such a terrible system!  According to the IRS, QB must supply us the form to either enroll for a PIN, or to try and retrieve a PIN!  So, can someone tell me where I QuickBooks I can find this form, I just keep going round and round!
