back door Roth IRA state distribution

Hi I did back door Roth in 2022. In my 1099R box 16 state distribution is 0. however in TT there is a page asking " where is this distribution come from" and it entered the distribution amount automatically and I cannot change it to 0.  In my state part, there is no entries show this distribution is Back door roth conversion.  I am in NC. does this mean this distribution is taxable in NC? thanks
