I've got your back to help fix the incorrect cash account, @DrOck8.
The balance you see on the Cash Flow menu is always the most up-to-date. The Banking or Transactions menu processes the data so it's included in your accounting. This data gets updated automatically once a day. You can always select Update in the Banking menu to get the latest available data.
Let's make sure that what's in your register is accurate before reconciling it. We can adjust it to zero and then correct your payroll settings. This way, you can use the correct bank account when running payroll. For more details, please see this article: Manage your payroll accounting settings.
