I have the same problem with Pennsylvania. Even though I reported my T-Bill income in Box 3, the state side is showing this as taxable and on top of that indicates I need to pay a penalty to Pennsylvania for underpayment. Can someone confirm that this is a bug in 2023 TurboTax? Is the only way to correct this is to manually remove the T-Bill income from the federal side and reprocess the state form? Thanks
