I'm having the same problem with my NC return for 2024. I've made entries like you suggested but the NC tax calculation does not change; TurboTax is treating all federal tax-exempt income as if it is coming from NC (instead of the correct 1.1% of the total being from NC). I've used the NC and XX (multiple states) split as suggested and tried having all $s as XX (with nothing for NC) but with no impact to the NC calculation.
This looks like a bug. Any ideas? Thank you.
