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.
- Click Save and Close.
I'm adding this article for more details: Disconnect or delete an account connected to online banking.
Then, if you want to upload your bank transactions manually in QBO, you can check out this article for the detailed steps and information: Manually upload transactions into QuickBooks Online.
