Im a US citizen married to a Philippine citizen, we are currently living in the Philippines. Im having trouble filing because she doesn’t have a SSN/ITN. How do i file?

I received my 1st stimulus check, but not the 2nd one. That is the reason I am filing. But my wife does not have SSN or ITN, so I am having trouble filing. What do I put on her SSN? Or how do I file?
