Welcome to the QuickBooks family, @gap4210.
I'm glad to see you dropping by here in the Community. I can share some insights about sending pay stubs in QuickBooks Desktop.
If an employee's last name is shorter than four characters, enter the entire letters in lower case. In your case, it would be the three letters and the last four of the social security number.
For additional information, I've attached an article about emailing pay stubs: Email pay stubs from QuickBooks Desktop.
