How can I get the correct payee details from the bank. each time I have a certain description the same payee is entered (first one ever downloaded)?

Good day to you, @shirley6.

QuickBooks Online (QBO) is dependent on the information provided by your bank. Thus, I recommend contacting your bank account for clarifications.

In the meantime, you can update your bank transactions by manually changing the payee. Let me show you how. 

1. Go to the Banking or Transactions menu.
2. Select the Blue tile of your preferred bank account.
3. Go to the For review tab.
4. Select the transaction you want to edit.
5. Change the payee of the transaction or information and click Add to add it in your bank register.
