According to the instructions, to request an extension of time to file your Ohio IT 4708,
check the federal extension box on Ohio IT 4708 and include a copy of the federal extension with the Ohio return or provide the federal confirmation number for the extension if electronically filed. Mail the IT-4708P generated in the program with your payment. To override the payment calculated, enter the amount in the Extension screen under the Ohio Composite Extension section.  The Lacerte program does not currently support electronic filing of extension for OH composite return.
