Can I change information on this payroll that in incorrect?

It's a pleasure to see you here in the Community. I can share some information about changing the pay period and amount in QuickBooks, @tatschwellservic.

Currently, in QBO you can edit the amount, but changing the pay period is unavailable once created. To fix this, you can delete and recreate the paycheck instead. To do this, you can run the Paycheck List report to view all the paychecks that you've created. Here's how:

1.  Log in to your QuickBooks Online account.
2. Go to the Reports menu at the left pane.
3. Search and choose the Paycheck List report on the Find report by name field.
4. Click the Funnel icon drop-down to choose a date.
5. Put a checkmark on the paychecks you need to delete, then click Delete.

Once done, you can now recreate the paychecks with the correct pay periods. Here's how:

1. Log in to QuickBooks Online.
2. Go to the Payroll menu and then choose Employees.
3. Select Run Payroll and then select the employees.
4. Enter the necessary information.
5. Click Preview payroll.
6. Select Preview payroll details or Submit payroll.
7. Choose Finish Payroll.
