Hi there,

I called Lacerte and after some time they were able to tell me the following - hope this works for you!

Go to screen 52 OSTC

Enter everything like you normally do for the state abbreviation, income taxed by another state, and tax owed to another state.

Then go back into the Income Taxed by another state line (open the detail box). Go to the second line item under the one you entered a number in already.  Enter the IT-BUS business deduction that is on the Ohio form. If it was the max then put $250,000.

Somehow this makes it work. The Resident Credit and the IT RC should calculate and be correct.
