So very sorry for the loss of your spouse. For your personal income tax return---for the year in which your spouse died, you can file a joint return and sign it yourself. Your daughter does not sign that one. Don't confuse the "estate" return with your personal individual/joint tax return. They are two different returns.
For the year that your spouse died, you can still file a joint return. That way, you will get the married filing jointly standard deduction of $27,700 (+ $1500 for each spouse 65 or older) which will lower the amount of income you are taxed on.
In My Info, you will need to indicate that your spouse died. When his name is in My Info, there is a screen early in the interview that asks "Do any of these apply to [name] ?’” where you will do that, and then a drop down will appear where you can enter the date he passed.
