Thank you for joining the QuickBooks Community, MF24!
You will want to contact our Payroll team for corrections in this case since the affected period is already in the past quarter. Just to add and for the sake of other readers, you can enter the lumpsum values of the pay, deductions, contributions, etc. when you've just started setup up the payroll feature: Add pay history to QuickBooks Online Payroll.
Check out the contact details of the QBO Payroll team: Contact Payroll Support.
You can also check out the help articles for QBO Payroll should you need them in the future. Just scroll down a bit and click More topics.
Feel free to go back to this thread if you have any other payroll concerns,
