Hi there, logiclayer. I can provide the steps for fixing locked-out accounts in QuickBooks Online (QBO).

First, let me assure you that your payment is secure. It's possible that the lock on your account is a temporary security measure. You can also contact our support team without logging in to your QBO account.

Here's how:

1. Go to the QuickBooks Support page.
2. Select your subscribed product on the dropdown button.
3. Then enter your question on the field.
4. Once done, click Continue to send it.

I've included a screenshot for your visual reference.

Please know about our support hours for Plus, Essentials, and Simple Start are Monday-Friday, 6 AM to 6 PM PT, and Saturday, 6 AM to 3 PM PT Advanced, any time, any day.

Additionally, once successfully logged in, you can update your Intuit information for security reasons.

Feel free to reply to this post if you still have login issues. I'll be here to help you.
