You can file head of household if you have a qualifying child and you did not live with your spouse for any part of the last 6 months of the year. In the program it first asked for your marital status which is married. Skip the part where it asks for the spouses social security number and continue on to add a qualifying dependent. Once you do that the head of household filing status should be presented to you and you can accept it. At that point you no longer need the spouses social security number. Please follow the interview screens carefully and in order.
