2016 death of infant 2 mos post birth, declared on 2016 taxes as dependant - how do you declare death of same child on 2017 taxes? Or, do you simply 'delete' dependant?

Granddaughter born 5/16; passed away 7/16

Helping my son file he/wife's taxes. Declared dependant on 2016 tax form, how do you now declare DEATH of infant on 2017 tax forms?

Need to file - refund is expected according to turbotax, but am stuck on this one detail.

The only option I see under "dependant" is DELETE or EDIT. Under edit, it does not offer any detail/correction/edit for death.
