Death

Hello Cs555, 

Hope you're doing well!  Please accept my sincere condolences for your loss!

Yes you may file a final tax return for your mom with TurboTax.  Make sure to call us if you happen to get stuck or something while working on her final return.  You can also have one of the tax experts review it before you file. 

Thank you but do I have to first have a notice from the court listing me as executor?

No, not necessarily.
