Allocation of Wages between States

I moved from Wisconsin to Ohio.  How do I ensure that I am only being taxed on the income earned in Wisconsin by Wisconsin and the income earned in Ohio by Ohio?  I'm specifically asking about W2 income.  The Wisconsin return allowed me to identify the amount earned in that state, but the Ohio return doesn't seem to have that option.  Do I need to identify the Wisconsin income as income being double-taxed in Ohio (so as to claim the credit for taxes paid in Wisconsin) or is there something else I have to do in the software?  Thanks!
