A payroll transaction was auto matched in the bank feed today. I did not create this rule and do not want it. How do I turn it off when it's not in my rules list?

You can turn off auto-matching by clicking the Gear icon under the Posted tab on the Bank transactions page.

Here is how:

1. Go to All apps, then select Accounting.
2. Click on Bank transactions.
3. Select the Posted tab and click the Gear icon in the top-right corner.
4. Toggle Automatic matching to Off.

Note that these changes will apply only to future transactions.
