Did you ever get this to work?  I am having the same problem - I have a return where tax was paid by a composite return on the Ohio client's behalf in two states.  I need to enter the income and the tax paid so that it flows through to Ohio IT RC and Ohio Schedule of Credits.  However, I do NOT want to create or file the tax returns for the two other states, since the firm already filed composite returns.  When I enter the state names, income, and tax paid in the Ohio credit for taxes paid to other states area, it does not flow through to Ohio IT RC and Ohio Schedule of Credits.
