Very sorry for your loss. For the year in which your spouse died, you could file a joint return. For the next two years after than if you have a qualifying dependent child or step-child you can file as a Qualified Surviving Spouse. If you do not have a dependent, then you file as Single.

If your filing status changes to Single, it is best to start a new account with a new user ID. It is too difficult to delete the embedded information from a spouse if you use the same account that was used for past joint returns.
