Chicago and Turabian Styles are nearly identical. Essentially Turabian aims to simplify some of the aspects of Chicago for students writing research papers not intended for publication.
The most important difference between Chicago and Turabian Style is the numbering system for notes.
Chicago uses a number in parentheses followed by a period, a space and then the source information (1. Chicago Manual of Style).
Turabian utilizes superscript¹ in the text of the paper and in the footnotes. The superscript number is followed by the source information (¹Turabian Style).
Like Chicago Style, Turabian utilizes different citation systems (Author-Date or Notes-Bibliography) and you should check your assignment instructions to determine which system your instructor wants you to utilize. For a paper written for the humanities you will most likely utilize Notes-Bibliography and for most other discplines (particularly the sciences) you would typically use the Author-Date system.
