When was your divorce final? If you were divorced in2025 you now file as Single.
If you used Turbo Tax last year you should start a brand new account for yourself and not transfer from last year. You can not remove a spouse or switch the order of names.
TurboTax will not allow you to remove the primary taxpayer on the return. And you should not try to change the order of names. If you were listed as the spouse and want to be the primary taxpayer now or delete the primary person, you will need to start a new return by logging out and starting over with a new account and new user name and password. You will not be able to transfer from the prior year.
Online is only good for 1 return per account. But you can use the same email address for 5 accounts. Start another Online return here and sign up for a new account

Filing taxes after a divorce
Filing Taxes After a Divorce: Is Alimony Taxable? - TurboTax Tax Tips & Videos
If your divorce was final at the end of 2025 your filing status for tax year 2025 is Single, unless you are the custodial parent of the children. In that situation you may be able to file as Head of Household. You will not file married filing separately if your divorce was final by December 31.
Start a new account with a new user ID. It is too difficult to remove all the embedded "spouse stuff" from an account that was used for a past year joint return. It will cause all kinds of errors.
Am I Head of Household?
If you qualify as Head of Household, when you enter your marital status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.
