Hello again,
In reference to my original question and in response to TomD8's answer, it looks like my son must pay DC taxes because he lived in DC for the entire 2019 (and he's still there). I don't think he should be paying CA taxes because he has been away from CA since June 2018. Please let me know if you disagree.
If you agree with my thought process above, should my son pay DC taxes on the fellowship, he received upon his graduation from CA University, to work at the Senate in DC?
What TurboTax plan would allow me access to the CA 540 for non-residents?
Thank you!!
