I worked four jobs last year(2016), why so I owe so much money to both federal and state??

I also had to amend my return because I forgot I had more than one W-2 coming to me. Is that why I owe? I always thought anything I owe was taken out of my paychecks. Also, saying I'm getting every tax break, then telling me I owe money tells me I'm not getting every tax break.
