How do I add the age amount to an employee's TD1 taxwithholding form?

Hey there fitwitch1-hotmai,

 Welcome to the QuickBooks Community. It's always great to see new faces! Making sure you're entering the correct information is important. I would be happy to point you in the right direction.

QuickBooks Online Payroll is aligned with government guidelines. When running payroll for your employees, the amounts are automatically calculated based on the government requirements for each employee. This means that you do not need to enter the age amount to the TD1. In addition, here is a helpful guide that will explain a bit more about Payroll deductions. I hope this helps!
