@ATX Bookkeeper  It's probably sourcing from the Auto Fill Contact Info box.

When you double-click on any given payroll tax form, the 'File Form' window will pop up.

On this window, in the top left corner, you'll find the 'Auto Fill Contact Info...' button.

This window's contents are shared where applicable across all payroll tax forms. Contains such information as Name, Phone Number, E-mail, etc.
