Can anyone help- QB is no longer giving me the option to choose which region I use when I log in?

You just need to select a region when opening a new blank QBO account. Once you've created it, you don't have to bother with the region anymore.

Nice to see your post today, userlbj.

You can use this link to log into your US account. From here you can switch accounts from different regions: https://app.qbo.intuit.com/app/login

What if I made the wrong selection during setup?  Is there an option to switch in this case?

Where is your company located?

Thanks for joining this thread, @51956. 

You can switch to other regions when you select the wrong one during the setup of your account. To do this, you'll have to cancel the current account, then subscribe again with the correct country.

Here's how:

1. Proceed to the Gear icon.
2. Choose Account and Settings.
3. Go to the Billing & Subscription tab.
4. In the QuickBooks section, select Cancel subscription.
5. Click Continue to cancel, then select Continue to cancel again.
6. Complete the remaining steps, then click Submit and cancel subscription.
7. Choose Got it. 

Then, visit our website to re-subscribe. Then, scroll down at the bottom of the page, then click Select a Country. Once done, you can set up your new QuickBooks account.

You can also contact our support team if you have further questions about your billing concerns. For detailed steps, please see this article: How and when can I contact Support?

Additionally, let me attach this reference you can check out to learn navigating your QuickBooks Online software and how to use its features: Get started with QBO.
