I cleared my return and started over but, my ex-wife is still showing up in the questions. Not the calculations but the questions. How do I delete her from my profile?

If you are no longer married and you were filing as Married Filing Jointly, you will need to create a new TurboTax account since you are now Single.  Clearing out a tax return that was filed as MFJ and is no longer filing with that status is very problematic.

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.

Online is only good for 1 return.  But you can use the same email address for 5 accounts.   How to start another return in the Online version
