I have a journal entry for payroll. I over payed myself so refunded the company the difference. I now can’t get the payment or refund to match with the journal entry.

Thanks for confirming, richardtitchener

We don't recommend editing the payroll journals, so the best course of action would be to create an additional expense for the overpaid amount (+ New > Expense) on the date that this was paid out, and then create a deposit (+ New > Bank deposit) for the date that this was re-paid. You can select the default payroll wage expense account on the 'Category' field on the expense, and the 'Account' field on the bank deposit, to ensure the net impact is zero. 

You can then exclude the original payment to yourself from the banking screen, rather than matching this, by selecting the checkbox to the left > scroll to the top > exclude. As the manual bank deposit should have the same date and amount as the re-payment, you should see the automated match to this on your bank feed.
