Hello, @Tia Grant.
I see you've been through a lot in trying to acquire the 10 digit pin for your E-file. I'm here to guide you, so this matter gets resolved.
The E-file 10 digit PIN has no expiry date. You can only ask for a new one through the IRS website if it's missing or lost. You must have clicked the remember this pin on the system thus creating an unusual behavior when entering your pin. To ensure that the pin goes through smoothly, please re-enter it again and be sure you've unchecked any boxes that require to remember the pin.
Also, make sure you have the most recent payroll update to avoid any disruptions while processing your E-file/E-pay in QuickBooks.
Keep me posted on how it goes. I want to ensure you can submit your form successfully. Have a good one.
