That is correct; if you work remotely in Nebraska, that is Nebraska source income even if your company is located in another state.
Did your company withhold Illinois taxes in addition to Nebraska taxes? In the lower section of your W2, boxes 15, 16, and 17 does it show both Nebraska and Illinois and have amounts for taxes withheld in each state? If so, you will want to file a non-resident Illinois return to get those withholding refunded.
