As ErikYou suggests, one normally would nest an enumerated list within an enumerated list to get this effect. However, in your case, this would in effect start a new list with its own counter. So, I would suggest you use the IndentedEnumerate environment defined below which starts the nested list so that its enumeration continues on from the previous list and yields:

##Notes:

## Notes:

• This is only set up for one level of nesting -- It will need further enhancements if more than one level of nesting if desired.
• If the first item is to be indented, you need to add \item[] before starting the IndentedEnumerate environment.
• If you wish this to work without the enumitem package package, the only tweaks necessary should be to modify how the label is specified for the indented list.
• The showframe package was used just to show the page margins.

\documentclass{article}

\setcounter{enumi}{\theListStartCount}%
\end{enumerate}%

\begin{document}
\begin{enumerate}
\item[]
\begin{IndentedEnumerate}
\item This is the frist item with indentation, so need \verb|\item[]| before this.
\end{IndentedEnumerate}
\item This is a normal item without any indentation.
%
\begin{IndentedEnumerate}
\item This is an indented item with a long text that causes a line break. Now, the enumeration is continued and the new line is indented.
\end{IndentedEnumerate}

\item This is a normal item without any indentation.
\end{enumerate}
\end{document}
