How do I report exempt-interest dividend earnings on a mutual fund with sources from dozens of states (and only with info on the %, not the $ for each)?

My provider gave me a state tax information sheet that breaks down the source of income only by percentage.  I don't know how to translate that into an accounting of all the states where I earned dividends (it looks like it's about 40 states).  This is just a couple hundred dollars we're talking about, total, in dividends.
