The confirmation of identity is sending to the wrong phone number

Welcome to the Community space, Chiann. I'm glad to help you to update your contact information in QuickBooks Online (QBO).

We can use the account recovery form in this section if you can't receive a confirmation of your identity on your phone or email on the file. We'll process your request within one business day. 

Here's how: 

1. Click the account recovery form.
2. Once the article is open, go to the I lost access to my phone or email address.
3. Click Recover my account.
4. From the ID Type dropdown, choose the identification you'll use to process your request.
5. Select the purpose of your request in the Reason for Request dropdown, and click Continue.
6. From the Personal info section, complete all details needed, and click Continue.
7. Type all information in the Sign in info section, and select Continue.
8. Click Continue below for confirmation to proceed with your request.

Please know that the steps I've provided above came from an article from a different country that we can utilize.

However, if you can log in to your QBO account, you can update your phone number by signing in to the Intuit Account Manager using your sign-in info for QuickBooks. From there, you can also update your login credentials. Here's how to do it:

1. Log in to your QBO account and select the profile icon next to the Gear icon. 
2. Click Manage your Intuit Account and from the Sign-in & security tab.
3. Input the new Phone number and enter your Password.
4. Click Save.

If the problem persists after following the steps, I suggest contacting our Technical Support Team. They will help you review your QuickBooks Online account's setup and provide the necessary assistance. Our experts have the tools to check your account and help you update your credentials.

Moreover, you can check this article to learn about securing your information by providing advanced security tools and systems in QBO: Verify your QuickBooks Online account with multi-factor authentication or two-step verification.
