How do I change the phone number or email so that when I log on to an unfamilliar computer the code will be sent to the place I want it to go?

Hello kd-motorsports,

We can log in to our Intuit account and update your security information there. You can follow these steps:

1. Go to this link and log in to your Intuit account: https://accounts.intuit.com/index.html.
2. Under the Sign In & Security section, go to the Two-step verification.
3. Update the phone number and follow the verification processes.
4. Enter the verification code and select Continue.
5. Save the changes.

You can also use this link for reference about the multi-factor authentication: Verify your account with multi-factor authentication.

After that, you'll receive the verification codes to the updated phone number. 

Keep us posted if you have additional questions about the process. Have a great day!
