My daughter worked here in NY for about about half a year and got a W2 from employer with everything needed. She moved to Israel in June and got Married in September to a Israeli citizen (no USA anything) and they live there. So as of December 31st 2019 she was married. So if you put married filing separate (since the husband does not have to file anything) I still have to put the SS number of the spouse that we don't have . So what do I enter in that field ?
