I still get this error as of today, but the circumstances may be different due to being a PA resident: my sect 457 distribution is not taxable in PA, so while I have an amount in box 11, box 15 says PA with the PA state ID number, box 16 is blank. This has been the case since I started receiving distributions, but this year TurboTax wants to match the amount in box 11 with state amounts.
