The Chicago Manual of Style by Chicago vs. Turabian: What's the Difference?
Chicago Style and Turabian Style citations differ only in the numbering of their notes. The Bibliography entry is the SAME for both.
In Turabian Style, a superscript 1 is used for endnote & footnote numbers in the text & at the beginning of each note. Example: 1 Turabian
In Chicago Style, the in-text numbering is in parentheses (1) & is followed by a period. Within the footnote, it is the number followed by a period. Example: 1. Chicago
