Something's gone wrong. My husband died in 2017, but when I logged in to my account, which I've had for 9 years, it addressed him. Personal info says I'm dead.

So sorry for your loss.  It sounds like you are trying to use an account that was previously used for a joint return with your late spouse.  And the information has become confused on the return.  You should start your own new account under only your name now.  It is too hard and confusing to remove all of the information from a joint return when you need to file as Single.  Unless you have dependent children you are still supporting, you cannot file a joint/widow return now; you need to use Single as your filing status for 2019.
