Correctly add custom table of content item [duplicate]

Index is incorrectly listed in the table of contents

I want to add a custom section to my table of contents. I know I can use addcontentsline{toc}{section}{title}. However, it doesn't use correct reference. When clicking on the item in the toc, it just jumps to the wrong section.

MWE:

\documentclass[a4paper]{scrartcl}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[pdftex,bookmarks=true,bookmarksnumbered,colorlinks=true]{hyperref} % http://ctan.org/pkg/hyperref
\usepackage{nameref}
\usepackage{makeidx}

\makeindex

\begin{document}
    \tableofcontents

    \section{Section 1}
    \index{bla}. \index{blub}.
    \section{Section 2}

    \addcontentsline{toc}{section}{Index}
    \printindex
\end{document}

To compile, run:

pdflatex file.tex
makeindex file
pdflatex file.tex
pdflatex file.tex

When clicking on Index it jumps to "2 Section 2" instead of "Index".

Since you are using one of the KOMA-Script document classes, all you have to do is to add the index=totoc class option:

\documentclass[a4paper,index=totoc]{scrartcl}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[pdftex,bookmarks=true,bookmarksnumbered,colorlinks=true]{hyperref} % http://ctan.org/pkg/hyperref
\usepackage{nameref}
\usepackage{makeidx}

\makeindex

\begin{document}
    \tableofcontents

    \section{Section 1}
    \index{bla}. \index{blub}.
    \section{Section 2}

    \printindex
\end{document}
