A trust has amortizable bond premium on both in-state tax exempt bonds and out of state tax exempt bonds. For purposes of preparing the state (Calif) return I should be able to reduce the interest income on the out of state bonds by the amortized bond premium attributable to such bonds. How do I generate that result? (I see 3 entry boxes - total municipal bond interest, in-state municipal bond interest and amortizable bond premium. If I use the drop down to enter the premium and then separately enter the premium for each kind of bond, entering the state for the premium on the in-state bonds, I get the wrong result. I've also tried various combinations of US/state and N/S without success). Help!
