When open to finder and going through any folder a gray question mark appears between the gear looking icon and the search bar. When the question mark is clicked a window pops up stating "The item can not be found" however all my files and everything are all there however. No matter what is selected the question mark still appears

hold command and drag the question mark off the toolbar. you had some custom toolbar item there that Finder lost track of. it's nothing important.
