Ohio State Tax non resident

I live and work in Texas.  My wife owns a rental property in Ohio.  The only Ohio money made is the money from that rental property.  It is about $6,000.  When I go through Turbotax and claim this along with the tax and insurance I have to pay it says we owe Ohio $103.  Seems strange that making so little that we have to actually pay.  I did notice that our federal income is listed on the Ohio state tax return.  

 

Does this sound right to you or should I leave out my federal income?
