I have W-2's from 2 different states. I lived in CO (and worked) from Jan-Dec, but I worked in Ohio from May-Oct. How should I appropriate my Income for each state?

CO currently calculates that I owe $415 in taxes when I include my Adjusted Gross Income and Taxable Income from my 1040. OH took $207 State and $136 Local on my 1 W-2 from there.
