How do I edit only the checking account a payroll check is posted from?

Hello, pjzyskconstructi.  

If payroll were posted to the wrong bank account, then you'll have the option to create a journal entry to transfer the funds to the correct bank account other than delete and recreate the paycheck or taxes in QBO.

Before doing so, I recommend getting in touch with your accountant for additional guidance in recording this. This way, we'll ensure the accuracy of your accounts after making these changes.

To create a journal entry:

1. Select + New.
2. Choose Journal entry. 
3. Fill out the fields to create your journal entry.
4. Press Save and close.

For more details about how to enter the debits and credits for wages and taxes, as well as a sample paycheck, please check the following article: Manually enter payroll paychecks in QuickBooks Online. 

Once done, run a payroll report to check if the amounts are accurate in your QBO. Also, I encourage checking our Employees and payroll taxes page for reference. There, you can read some of our great articles and learn some tips in managing your payroll.
