Ah, one other idea. n[272] is probably n[230] plus n[42]. I suppose that’s TMT6plex plus Acetylation. Is that possible? If so, then maybe we need to teach SpectraST about it. But the relative ratios of the numbers I quoted below are still quite odd and raises a red flag. Is there a reason to expect so few peptides ending in lysine. Maybe it’s all fine.

I thought TMT6plex is n[230]. You seem to be adding a very different mass to the n terminus than the TMT6 that I know, or I’m confused. Maybe your n-terminal mass mod is wrong? Or maybe you’re not using TMT6? The other numbers you show are very puzzling: E,Glu->pyro-Glu: 215 K,TMT6plex: 197 Q,Gln->pyro-Glu: 101 n,TMT6plex: 2879 K,TMT6plex should be about half of n,TMT6plex and it’s not. And a scenario where E,Glu->pyro-Glu is greater than K,TMT6plex is hard to fathom. These relative counts don’t make sense. I suggest checking your mass mods for the original search very carefully and redoing the search.
