How do I connect more than one bank account for automatic downloads of expenses etc.

Hi there, @turquoiseturtlec. 

I can help you add your other bank account in QuickBooks Online.
 

To connect your other accounts, you'll have to create a new one in your chart of accounts, then connect your bank from there. You must also have an online banking account to successfully connect this to QBO.
 

Here's how to create a new account:
 

1. Go to the Gear icon and select Create a new account. 
2. Click the New button. 
3. The Account window opens.
4. For the Detail Type drop-down menu, select Bank.
5. Assign a name and all other information.
6. Specify whether this is a sub-account of another account.
7. Provide the Opening Balance of the account.
8. Click Save and close.

Through the chart of account, here’s how to add your bank:

1. Go back to your Chart of Accounts.
2. Select the new account that you’ve created a while ago.
3. From the View register (or Account history) drop-down, select Connect bank.
4. Follow the prompts to connect your bank account.

If you have multiple accounts to connect with the same online banking credentials, you can repeat these steps for each account before moving to connect all of them at the same time.

In addition, here's an article you can read to learn more about the parent and subaccount setup of your chart of accounts: Create subaccounts in your chart of accounts in QuickBooks Online.

That's it. If you have any other questions or would like me to clarify anything else about adding your bank account, let me know by leaving a comment below. I'm always glad to help in any way I can.​ Have a good day.
