if you are doing part-year tax returns, it takes a lot of work and extra go-rounds to understand how to allocate the interest between the two states. Once you are back to a full year resident, it's easier.
And also, on the followup page that asks about the source of the tax-exempt $$, you are allowed to break out your own resident state's bond tax-exempt amounts for proper exemption of a sub-portion of those $$ from that state's taxes. TTX handles them all properly once you understand how to do it.
