Macintosh, location of tag file?

Hi folks,

just got a new 1TB SSD drive installed in my MacBook Air and consolidated music from old internal drive and external drive. I also started with a clean system install and new Roon music folder. Along the way, I lost the self made tag (modern classical) on a bunch of albums my wife likes. I’m prepared to go back and make the tag and add it to albums, but thought I’d ask: is there a “tag” file somewhere in Roon or preferences that I can rescue from Time Machine and put back in? If it’s not a separate file, I don’t think using an old TM or Roon backup will work because music file locations are not the same as they were.
