Now that I have finished our joint return I would like to file a return for my son who passed away in 2015. I am the executor of his estate.

How do I do this for the situation i described above?

TurboTax Online can only prepare and e-file one federal return and up to five state returns. To file a return for someone else, you must create a new UserID for that person. You may create a new login (up to 5) tied to your same email address if you'd like.
