So I resolved this issue today 4/10/2025
Go back to your K-1 entry for Box 18
For Box 18 once you enter all the info from the K-1, the next screen asks to list the state that paid the (keyword) tax-exempt interest income. Only enter the State and amount for code A. Don't enter anything else.
This will clear up the error.
It doesn't want the state for any other codes, just A.
I had A, B, and C with amounts. The next Screen only enter the state and the amount.
Code B and C are not Tax-exempt interest income amounts.
B is tax-exempt income - this is different from tax exempt interest income
