State tax filing

Thank you for your response @MaryK4! A follow-up question for you if you don't mind... The W-2 does not differentiate the training period versus work done in CA, so the state wages (box 16) for both CA and IL include the entire 2022 wage amount. Based on what you stated, the IL state wages should only include the wages for the training period, and the CA wages would include the rest. How should I report the W-2 numbers on the state tax returns? Do I need to request a revised W-2? Thank you in advance!
