The usual reason that you would end up with no MS2 chromatograms in a PRM experiment is that Skyline did not find any MS2 scans that isolated an m/z which was close enough to your peptide.
The "Method match tolerance m/z" specifies how close the isolation m/z in a PRM experiment has to match your peptide. This setting is on "Settings > Transition Settings > Instrument" and has a default value of .055.
The other thing that often happens in PRM experiments is that there is some other peptide in the document whose m/z is a better match for the MS2 scan than the peptide that you hoped it would match. If MS/MS Acquisition Method is "Targeted", then Skyline will match any particular scan to only one peptide in your document. If you were hoping that your scans would be able to do some sort of double duty, and be applied to all peptides within some small m/z range, then you should change the Acquisition Method to "DIA", and perhaps use the isolation scheme called "Results Only".
It does not look like this is your problem, since you only have one peptide in your whole document. However, if you had other peptides with really close m/z's that you recently deleted from your document, you might want to try doing:
Edit > Manage Results > Reimport
and see whether this problematic peptide gets its MS2 chromatograms after you have removed all of the other peptides from your document.
If you send us your files, we can probably tell you what is going wrong.
In Skyline, you can use the menu item:
File > Share > (complete)
to create a .zip file containing your Skyline document and supporting files including extracted chromatograms.
If that .zip file is less than 50MB, then you can attach it to this support request. Otherwise, you can upload it here:
You should also send us at least one of your raw files.
