Not sure if this is helpful at all but any automatic payroll data entered into QuickBooks I'm pretty sure is "locked in" and unfortunately QB support knew nothing on what to do or how to help so I ended up doing a journal entry to move the wrong transactions out of the account so I could reconcile it and it wouldn't be permanently unbalanced. 

Also, QuickBooks Online has a really bad issue that if you change the bank account payroll comes out of, there is a second process many don't know that you have to manually go in and also change the chart of accounts so it doesn't record into the wrong account, because if it does, only a journal entry will move it.  So anyone who can't find transactions to match, you may want to check other accounts to see if put in the wrong one.
