Will I be penalized when QB inaccurately reported duplicate payrolls for the same day on the payroll summary report?

Hi there, @rishanna.

No, you won't be penalized since the Payroll Summary report is intended for reporting purposes only. 

You'll only be subjected to penalties if the payroll taxes withheld from your employee's paychecks aren't or improperly forwarded to the IRS. This will also include depositing the wrong amount of withholdings or for incorrect filing.

The data that you can see in this report only shows the amounts from the paychecks and prior payroll that you’ve created.

However, you can still delete the duplicated paycheck that you've created to correct your payroll records. Here's how:

1. Go to the Workers or Payroll menu and select Employees.
2. Under Run Payroll, click Paycheck list.
3. Select the check(s) you'd like to delete.
4. Click Delete and confirm the deletion by selecting Yes.

In addition, you can customize your Payroll Summary report to easily review the data that matter the most to you. You can also memorize this report to save its customized settings.

Please let me know if there's anything else I can do to be of assistance. Just place your concern by clicking Reply and I'll get back to you. Wishing you and your business continued success in all that you do. Have a great weekend.
