this can be complicated. your resident state should tax all out-of-state municipal dividends/interest. some states tax all their municipal interest. my state, Illinois, is more complex. certain municipal interest/dividends are taxable others are not. so for Illinois you would need the source of those MUNI dividends
In Illinois all muni interest/dividends are added on line 2. then there is schedule M where the amount of interest for each bond which is exempt is entered and the total ends up a a subtraction
