This a hugely helpful site, and I did my best to research my question before asking it, but my situation seems to be a bit too specific.
My wife is a full-time PhD student at a Canadian university where she received a scholarship of ca. $20,000 in 2018. However, since she is at the dissertation writing stage, she doesn't need to be physically in Canada and moved to the US with me in 2017, so we are both resident aliens of the United States for tax purposes (I'm on H1B and she's on H4). Do we need to indicate her scholarship as taxable income? Thank you very much!
