If you need the validation number sent to a cell phone, you need to make those changes in your Account Information.
Log into your TurboTax account. Top of the screen, choose My Account > Account Settings > Security input your cell phone there and be sure to do the Verification. Once your cell phone number is verified, the next time you have the code sent, you will be given a choice to send the validation code to your cell phone instead of email.
