On Form 1099-INT Worksheet, under Box 8 where it asks for "State ID where exempt interest was earned", I have more than 1 state. Says to see Help. How do I do this?

How do I enter more than one state on the 1099-INT worksheet under Box 8 where it says State ID where exempt interest was earned.  Says "If more than 1 state, See Help", but I can not find an answer.
