I just gave an employee a raise. The raise was retro active back to 1/1/19. How do I adjust her paycheck this pay period to calculate that ? Thanks !

Good day, @gbeach16.

Thank you for choosing QuickBooks in running your business. Let's work together to resolve your payroll concern.

To adjust the employee's paycheck, you will have to manually calculate the extra amount to add on her upcoming payroll. Once you have the details, here's what to do next.

First, create a payroll item under the employee name:

1. Click Workers.
2. Under the Employees tab, select the employee name.
3. Click the Edit employee.
4. Go to the How much you pay *Employee name* section and click its Edit icon.
5. Create a payroll raise item. 
6. Enter the raise amount on the specific field.
7. Click Done to save changes.

Next, create a paycheck:

1. Click the Plus icon.
2. Choose Payroll.
3. Select the pay schedule and click Continue.
4. On the Run Payroll screen, select the employee.
5. Enter the regular pay hours. 
6. On the Raise hours field, enter the missed number of hours from January to present. That way, you're able to add the remaining amounts.
7. Update other necessary information.
8. Continue the prompts in creating the payroll.

That should get you on the right track, @gbeach16. I'm still here to help you more if you have other payroll questions. Just add a comment below. Wishing you and your business continued success!
