Is the paper Employee Direct Deposit Authorization form necessary even though the employees have filled out their information in the Workplace App?

Let me provide some details on this, Kerrym.

The Employee Direct Deposit Authorization form is important to fill out to utilize the efficiency of direct deposit, as well as to stay legally compliant for payroll. If you're referring to the Workforce App, yes, you'll need the form to ensure the routing and account numbers match the ones on your bank accounts as well as your bank details. 

On the other hand, if you're referring to the Workplace third-party application, I suggest contacting their support team so they can guide you through the process. 

Furthermore, QuickBooks uses pay schedules to make payroll more efficient. Check out this article for reference: Create and Run Your Payroll.
