State tax filing

Thanks for clarifying the 4708 for my brother.  I will only include him on that form. 

 

OH's instructions are not clear to me.  They say you can file the 1140, the 4708 or both.  SInce I'm only including my brother on the 4708,  do I need to file the 1140 for me as well?

 

THank you very much!
