I have been divorced for 17 years and do not have a spouse. How do I get rid of the spouse on personal profile?

If you are going to use the TurboTax online editions then you will need to create a new account with a new User ID since you are now filing as Single.

Are you in the right account?   You should have your own account now.  Are you using an account that was used when you were married?  You need to setup your own account and not transfer from 2023.  

You need to log out of this account and probably clear your cache and cookies and reboot your computer.
