When you first connect a bank in QuickBooks Online, only the accounts you select at that time are linked. Any new accounts opened at the same bank later won’t be added automatically—you’ll need to connect them manually.
To add the two new accounts, go to All apps > Accounting > Bank transactions > select the Link account drop-down > Add account. Search for the same bank, sign in with the client's banking credentials, and choose the two new ones from the list. Map them to the correct accounts, then connect.
