How to Use Chicago Style in LaTeX
The fix
For Chicago style in LaTeX, use biblatex-chicago. Load \usepackage[authordate]{biblatex-chicago} for author-date, or [notes] for notes-and-bibliography (footnote) style, add \addbibresource{refs.bib}, cite with \autocite, and print with \printbibliography. Compile with biber.
Example
% Author-date:
\usepackage[authordate,backend=biber]{biblatex-chicago}
\addbibresource{references.bib}
Text \autocite{smith2020}.
\printbibliography
% Footnote style: use [notes] instead of [authordate].Frequently asked questions
