Hi there, @jacques-tessier.
I want to make sure your concern is taken care of. May I know how you recorded the transfer in QuickBooks Online? On the other hand, if you match banking transactions, ensure the online banking transfer date record is the same as the transfer date created in QuickBooks. This will make sure you're able to match the transactions.
In addition, is the current bank and new bank account are different financial institutions? If you have transferred funds from the current to the new account, you can zero out the new account by recording a transfer back to the current account.
You also mentioned that QuickBooks shows the transaction in your current but no action in the new bank account register, that doesn't double the balance from there. And the later part, recording as transfer doubles the balance in the new account. I will appreciate it if you add more details in this scenario.
Moreover, I'm adding these articles for more details about matching transactions and account reconciliation:
Feel free to fill a comment and share more clarifications. I'm always here to help you more. Have a nice day!
