First time preparing an Ohio return, I have a NR that got a K-1 from OH with state W/H. It seems like OH calculates in Part A of the IT NRC the Depreciation adjustment twice? Can anyone confirm that this is correct? 

The client also got a K-1 for Columbus. If the Columbus withholding is correct, do I have to file a IR-25? It would seem from the instructions that I would need to file. Although, I saw on a different thread (see link below) that he might not be required to file. https://accountants-community.intuit.com/questions/878511-how-do-i-electronically-file-ohio-city-inc...
