Sch. C T/P worked in 5 states how do I divided up between states

[mrichman333]

OK, I have a sch. C T/P that has 1099-misc's from 5 states, so what I did was enter each 1099-MISC on the schedule indicating the state thinking, well, Hoping it would divide the income up.  Well it didn't.  Tried to go to the state return and add the proportion of income belonging to that state but that IS NOT POSSIBLE to do.

Any ideas?
