Was married until late december had grand daughter for over half year want to file joint taxes with depenadnt

[RichardG · Accepted solution]

You can only file a joint tax return with a spouse.  Since you were unmarried on the last day of the year, you should file as single, or you may qualify to claim head of household status.  Please enter your grandchild in TurboTax to see if she qualifies as your dependent for 2016.
