It's great to know you were able to download and add the sub-accounts, Angmann.

The option to connect both parents and their subaccounts is unavailable in QuickBooks Online (QBO). If you try to connect both, you’ll encounter an error message that the account is already connected.

In this case, we need to choose on what account you'll need to connect for your Online banking. If the transactions are downloaded to one account, just connect only the parent account. For transactions that are downloaded to the individual accounts, we can connect the subaccounts. 

When reconciling your accounts, we only need to reconcile the parent account since all transactions in the subaccounts roll up into it. See About bank or credit card subaccount setup article for more details about this one.

Feel free to visit our Banking page for more insights about managing your bank feeds and reconciling accounts.

You can always count on me if you need a hand with creating bank rules or any QBO related. I'm always here to ensure your success.
