I'm getting conflicting google/turbotax answers on this. I'm filing a nonresident return for California. I spent 4 days there and my state wages is $1200. Google is telling me that HSA contributions made by my IL employer are added back into my AGI and I owe money to California. Turbotax (2019 answer) says nonresidents can deduct HSA contributions via "misc. adjustment screens" because contributions were made by my IL company and not subject to California income. If I do this, I get a refund of $20 instead of owing tax.
What is correct?
