How do I enter employees into quickbooks that are not employed any longer but I need to add their hours for w2's, We changed payroll methods in middle of year

Helping you enter your employees' data in the system is my priority, @denbpage@gmail.c.

You can enter the historical payroll information for your employees so this will be reported in their W2's. 

To do that:

1. Go to the Workers menu at the left pane to get to the Employees page.
2. Select the employee to open the information, then Enter prior pay details. 
3. Enter the necessary information.

Repeat these steps for all employees paid this year. For more information about the process including a short clip for the procedure, I recommend checking out this article: Learn how to enter pay info for employees in QuickBooks Online Payroll.

To add up, you can always utilize this reference to guide you in preparing and filing your W2's: Learn about answers to your most common W-2 questions so you’re prepared for tax season.

You can always get back to me if you have further questions about this or with QuickBooks. I'd love to help you out. Take care!
