I am filling tax for 2024 which i was a student and lived in PA. Starting from 2025 i am working and living in IL. Should i keep my address and job as was in 24?

No, you don't use your former address in PA, you use your current address on your tax return.? Refer to the TurboTax article How do I change my address with the IRS?

Please clarify what you mean by keeping your job as was in 24. I don't understand what you mean.
