How to make an entry in the table of contents for the bibliography

Question

Question

In a document of class scrartcl, I would to make an entry in the table of contents for the bibliography. Currently the table of contents contain entries for any notation of \section{} and \subsection{} in the document.

My trial

The only pseudo-solution I found was to create a section bibliography and then remove the standard bibliography heading.

\section{Bibliography}
\renewcommand{\refname}{\spacedlowsmallcaps{}} % For removing the bibliography heading
\bibliography{/Users/remi/Documents/Biologie/Literature/BibTex/Proposal-cited2}

However, this solution makes an extra spacing between the section header (Bibliography) and the first reference.

Extra Formatting Info

Here are a few lines of code at the beginning of the document that you might need to know to answer

\documentclass[
fontsize=10pt,
paper=a4
]{scrartcl}

\linespread{1.5}

\usepackage[round,mcite]{natbib}
\bibliographystyle{plainnat}

EDIT 1

After @esdd's comments. I have tried the following

1. Adding bibliography=totoc to my document class. It produced the following error message

   (./ResearchPlan_0.0.1.bbl Runaway definition? ->\protect \protect \<>-\textls {\protect \begingroup \-command \ETC. ./ResearchPlan_0.0.1.bbl:1: TeX capacity exceeded, sorry [main memory size=5000 000]. \reserved@ a l.1 \begin{thebibliography}{24}

   ./ResearchPlan_0.0.1.bbl:1: ==> Fatal error occurred, no output PDF file produ ced! Transcript written on ResearchPlan_0.0.1.log.

2. Adding \KOMAoptions{bibliography=totoc} right before \begin{document} but it doesn't change anything (I typesetted several times).

Here is the list of files in the log file.

Answer 1

It could be that you use an older version of KOMA-Script.

Please run the follwing MWE three times (I included a small bib file with package filecontents, resulting with one warning) and check the log file. There you should find at the end a list of used class and packages and version numbers (created with command \listfiles in the mwe). Add this list to your question please.

Edit: I added the renaming of "References" to "Bibliography" in the MWE and how you can change the font for the heading "Bibliography" (You find the changed parts in the MWE marked with <=======).

Please check my answer to this question to learn how to rename "References" (with more explained code).

The documentation of KOMA-Script you should have on your computer. Please try texdoc scrguien for the english version or texdoc scrguide for the german version on your terminal/console.
