So sorry for your loss. Your spouse passed away in 2022, so for 2022 you could still file a joint return using the same account you have used for a long time. But now, for 2023, your filing status is Single. If you try to use that account that has been used for joint returns, it is going to be messy and cause errors, because it is very difficult to remove all of the spouse information. That is why it is suggested that you create a new account for just yourself. Keep a record of how to access the old one in case you need to refer back to it.
