Hi there, emcllcja.
If you haven't run your first payroll in QuickBooks Online, then yes, you can add the payroll information through prior payrolls.
Here are the steps:
- On the left panel, click Workers.
- From the Employees tab, click the employee's name.
- In the employee's profile, click the Enter 2018 prior pay details button. Note: Make sure to enter the employee's pay schedule and pay rate so you can see this option.
- Follow the on-screen instructions and enter the payroll history.
- Click Done.
You can also check this article for more information: Prior Payroll Overview in Online Payroll.
Otherwise, contact one of our Payroll Support Specialists if you no longer have the option, or if it affects multiple paychecks.
Here's a link where you can get our contact information: https://payroll.intuit.com/support/contact/?infosrc=qs&service=64.
Feel free to reach out to me if there's anything else you need. Thanks.
