Stopping the automatic updates for your bank account is my priority, @lduque-bluewayis.
When you connect your bank account in QuickBooks Online (QBO), it'll automatically download your recent transactions. To get this stopped, you'll want to consider disconnecting your online bank account from QuickBooks.
Click Banking from the left menu.
Select the appropriate bank account you want to disconnect.
Hit the pencil icon, then select Edit account info.
Put a checkmark in the Disconnect this account on save checkbox.
