To-do-notes in separate TeX File, but without \listoftodo in main doc

Question

I am using the todonotes package and have three requirements, the first two which the MWE already does:

1. Obtain a list of todo notes in a separate auxiliary file. This can easily be obtained via the \listoftodos as per the similarly named question referenced below.
2. Have the \todo appear in the document -- also works.
3. What does not yet work: I do not want the list of todo to appear in the header of this document.

The MWE below generates (after two runs):

The correct result should be only the two todo notes in yellow and pink, and the .tdo file needs to be newer than the .tex file

Notes:

• Did not automate the testing of the case where the MWE is run as is, and then upon second run the \listoftodos is commented out -- This will seem to produce the desired result, as an older .tdo file exists. However, I would prefer a solution that yields the correct result upon first compile.

Background:

• I have numerous small files and having a list of todo in each file is not that helpful. My plan is to post process all the individual todo auxillary files to obtain a single document that has all the todo notes along with links to the files that created them.

Code:

\documentclass{article}
\usepackage[colorinlistoftodos]{todonotes}%
\begin{document}
\listoftodos% Want the temporary file generated
\bigskip
\todo[inline,color=yellow,caption={Fix me}]{There should be no text above this line (as if listoftodos was commented).}
\IfFileExists{\jobname.tdo}{%
    %  Yeah, we have the temporary file
    \todo[inline,color=red!20]{Temporary .todo file exist. 
      But need to ensure that it was not left over from a previous run...}
}{%
    \todo[inline,color=red]{Failed: No .todo file...}
}
\end{document}

Answer 1

You just want \@starttoc without the file input:

\documentclass{article}
\usepackage[colorinlistoftodos]{todonotes}%

\makeatletter
\newwrite\tf@tdo
\immediate\openout\tf@tdo\jobname.tdo\relax
\makeatother

\begin{document}    
\bigskip


\todo[inline,color=yellow,caption={Fix me}]{There should be no text above this line (as if listoftodos was commented).}


\IfFileExists{\jobname.tdo}{%
    %  Yeah, we have the temporary file
    \todo[inline,color=red!20]{Temporary .todo file exist. 
      But need to ensure that it was not left over from a previous run...}
}{%
    \todo[inline,color=red]{Failed: No .todo file...}
}
\end{document}
