Let me lend a hand to help you with your subscription concern, @hyount.
First of all, I want to thank you for your interest in our QuickBooks product. In your case, since you've signed up for the trial version in the wrong country, you'll want to create a new trial account or new subscription to the correct one.
You can check this link to choose and subscribe to QuickBooks Online with the correct country: Choose your country.
I'm also adding this article to know more about how to get started with QuickBooks Online: Get started.
