Thanks for getting back to us, @kbbk.
As of now, QuickBooks Online (QBO) currently doesn't support Tyro bank. However, you can submit a request for it to be added. Here's how:
- In QBO, go to the Banking menu at the left pane to get to the Banking page.
- Click the Add account button at the top right.
- Enter Tyro in the search field, then select the Request support for your bank option at the bottom.

- Paste the bank's URL in the desired field and hit Request.

For more information about the process, refer to this article: Find your bank account when you connect to online banking.
Just in case, I'll add this article for future reference: Add and connect to a bank or credit card account.
Please let me know in the comment below if you have any other concerns. I'm always here to help. Have a great day!
