Filling the Online OCI Registration

[ImmiFAQ]

I received my US Citizenship Certificate few days back and I applied for my US passport which may yake 4-6 weeks. I am planning to apply for the OCI card for myself and my 4 month old daughter. So I choose the type as family group on the application and my question is which passport details do I need to fill on the application for myself.
