TurboTax cannot do anything about someone using your identity to file a tax return. It is up to the IRS.
What happens if someone filed taxes in your name?
When you discover another a tax return has been filed with your Social Security number, you'll use IRS Form 14039 to alert the IRS. When you complete this form, you'll indicate that someone has stolen your identity and it has affected your tax account since they have filed a return using your identifying information.
