Thank you, @Opus 17!
Ok, sounds like you're agreeing with my summary:
I figured she's paying ~$19k and we're only paying ~$9k so we can't claim her as a dependent.
So getting back to my original questions:
- Would the picture presented above get her a sizable refund or am I wasting my time to file for her?
- How would I determine whether I need to file a state (IL) return for her, as well?
