How to appear Appendix in list of contents?

Question

I wounder if you could help me to appear (Appendix A) in list of contents. my code is:

\documentclass[12pt]{report}
\usepackage{times} %Times new roman font
%\usepackage{mathptmx}

\usepackage[top=2.5cm, bottom=2.5cm, left=3.5cm, right=2.5cm]{geometry}
\usepackage{amsfonts,amsmath,amssymb}

\usepackage[colorlinks = true,
            linkcolor = blue,
            urlcolor  = blue,
            citecolor = blue,
            anchorcolor = blue]{hyperref}


\begin{document}
\chapter*{Copyright}
\addcontentsline{toc}{chapter}{Copyright}
test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test Appendix \ref{app:benchmark}
\newpage

\tableofcontents
\addcontentsline{toc}{chapter}{Contents}
\newpage


\appendix
\makeatletter
\makeatother

\chapter{}

\section{IEC microgrid data}
\label{app:benchmark}
\begin{itemize}
\item Utility: rated short-circuit MVA=1000, f=60 Hz, rated kV=120, $V_{base}$=120 kV.
\item Distributed Generations (DGs):
\begin{itemize}
\item DG1, DG3: synchronous generator with rated MVA=9, f=60Hz, rated kV=2.4, Inertia constant H=1.07 s, friction factor F=0.1 pu, Rs=0.0036 pu, $Xd$=1.56 pu, $Xd^\prime$=0.296 pu, $Xd^{\prime\prime}$=0.177 pu, $Xq$=1.06 pu, $Xq^{\prime\prime}$=0.177 pu, $Xl$=0.052 pu, $Td^\prime$=3.7 s, $Td^{\prime\prime}$=0.05 s, $Tq0^{\prime\prime}$=0.05 s.
\end{itemize}
\end{itemize}
\section{Distributed energy source data}
\end{document}

Answer 1

I have added Appendix A that appear into list of contents using \usepackage[titletoc]{appendix} and \begin{appendices} .... \end{appendices}. Is it the result you wanted to achieve?

\documentclass[12pt]{report}
\usepackage{newtxtext, newtxmath}     
\usepackage[top=2.5cm, bottom=2.5cm, left=3.5cm, right=2.5cm]{geometry}
\usepackage{amsfonts,amsmath,amssymb, lipsum}
\usepackage[colorlinks = true,
            linkcolor = blue,
            urlcolor  = blue,
            citecolor = blue,
            anchorcolor = blue]{hyperref}
\usepackage[titletoc]{appendix}

\begin{document}
