Does the oxygen burned from fire turn into carbon dioxide?

Not on its own, and it depends on what is burning. A fire can only produce carbon dioxide if the substance burning with the oxygen contains carbon. And even then, if there are other elements, you will get more substances as products. Carbon will produce carbon dioxide and usually some carbon monoxide as well. Hydrogen will produce water vapor. Sulfur will produce sulfur dioxide. Magnesium will produce magnesium oxide.
