You can’t prepare the Form 8379 directly in TurboTax Online, but responding to the injured spouse relief questions during the tax interview will generate the form. If you click above on “See entire answer” it explains that you need to skip the questions about innocent spouse relief if you want to file as an injured spouse (Form 8379). Above you’ll also find instructions for preparing Form 8379 to mail to the IRS if you’ve already filed your federal tax return.
So, i haven't filed it yet but need to do one. So will it send electronically when i finish or do i have to mail it to?
Yes, if you e-file your return, Form 8379 will be transmitted along with it.
