Deceased tax payer

Firstly, I'm so sorry for your loss.

But yes, you can file a return for your daughter and her dependents, though you won't be able to file that return on your account. You will need to create a separate account for her. You'll be able to show that the return is being filed for a deceased person on the 'Taxpayer Information' page of the 'Personal' tab. From there, the software will walk you through any additional information you need to enter.
