center tablenotes

Question

I have a problem in aligning the table notes to the left (at the height where also the table begins) and in forcing the text to be tiny (use it for a cheatsheet). Do you have a solution?

% page setup
\documentclass[]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{enumitem,booktabs,cfr-lm}% aufzahlungen mit erklärung nach Tabelle
\usepackage[referable]{threeparttablex}
\renewlist{tablenotes}{enumerate}{1}

% geometry
\usepackage[landscape]{geometry}
\geometry{headsep=\baselineskip}

% table
\usepackage{ragged2e} % for \Centering and \RaggedRight macros
\usepackage{booktabs, tabularx} % for well-spaced horizontal lines
\newcolumntype{C}{>{\fontsize{4}{4}\selectfont\raggedright\arraybackslash}X}

%----------------------------------------------------------------------------------------------

\begin{table}
\tiny
 \begin{threeparttable}
\begin{tabularx}{0.22\textwidth}{@{}*{2}{C} @{}}
    \toprule
\textbf{Congenital} & \textbf{Erworben} \\
\midrule
\begin{itemize}[leftmargin=*, noitemsep]

    \item B\tnote{2} 
    \item C \tnote{3}
    \item seltene Aetiologien\vspace*{-\baselineskip} 
\end{itemize}&
\begin{itemize}[leftmargin=*, noitemsep]
    \item A
\end{itemize}\\
    \bottomrule
    \end{tabularx}
\endtabularx
     \begin{tablenotes}
     \begin{tiny}
      \item[1] "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."

 \end{tiny}
    \end{tablenotes}
 \end{threeparttable}
\end{table}

\end{document}
