College student with military parents doing a remote internship

Hi All,

Just finished my daughter's federal tax return and trying to figure out where we need to file her state. My husband is USAF AD and we are TX residents (no state income tax, yay!). We have not filed a state return for our daughter (college student that we claim). She had an internship (headquartered in DC) and made $7,300. She also worked at her University and made $675 (SC). She entered school out of VA, but we live in IL right now (temporary, headed back to VA this summer). She listed this as her address for 1099 and W-2 purposes, but has never lived here. Where are we paying state taxes to? She also has a little investment income. Help!!
