A payroll was posted to an incorrect cash account. How do I fix that?

Hello there, @arbe.

Let me share with you the steps on how to correct your paycheck that was posted to an incorrect bank account.

Since editing a manually created paycheck is unavailable in QuickBooks Online (QBO), you have to delete and recreate it again. This way, you can correct your records. 

Here's how:

1. Click Workers, then Employees.
2. Select Paycheck List under Run Payroll,
3. Change the date range if necessary. Then, select the paycheck you want to delete.
4. Click Delete.
5. Mark the checkmark box to confirm the deletion and select Delete Paycheck.

Once done, recreate again the paycheck and make sure to select the correct bank. 

For the next steps, you can now print your paychecks, or pay your payroll taxes.

Additionally, you can run some payroll reports in QuickBooks. This way, you can get a closer look at your business's finances and view useful information about your business and employees. 

I'm just a reply away if you have other questions with the QuickBooks Online Payroll. Just add the details of your concerns in this thread and I'll help you out.
