Unfortunately you cannot lock your password.
In many cases this is occurring because an incorrect user id is being
used to attempt to login. This is occurring because your browser
remembers certain information and as you begin to type your user id it
pre-fills the incorrect user id. Please try the steps below to determine
if this is what is causing the password reset.
- Go to the Login screen on TurboTax.com and select the I forgot my User ID or password option to sign back into your account.
- Once you successfully reset your password and get logged into your account select My Account > Account Settings.
- Once in account settings select Profile and verify your User ID
