After you file

I'm running into this while trying to file taxes, hence I'm asking here.

 

I'm being asked: "Are the words "Not valid for employment" on the dependent's social security card?"

* Unfortunately, I don't have the SS card (my ex does), so I don't for certain. If I can know why that phrase would be on the card, or not, I can make a solid guess about whether or not the phrase will be on my dependent's card.
