I can't speak for all the various installations of Out of the Park.
I usually use a custom installation folder location so the logos end up in the following location: OOTP installation folder \ data \ logos
If you use Steam or Origin, you may be able to find them in your documents folder.
C:\Users\Your User Name\Documents\Out of the Park Developments\OOTP Baseball 19\logos
In regards to changing or loading a different logo...
1. Start Perfect Team and once you see your team, click your team name, then select Customize Team Design.
2. You can use the logos on the left side or use a custom one by
clicking "Advanced Settings" on the right side.
3. If you select Advanced Settings, you see your logos on the left side of the screen. One is the primary team logo and the secondary logo is the one that you can see next to your team or in the League Standings (as a tiny icon).
If you click on "Select", you can browse to your custom image/logo location (if you created your own one or found another logo that you like).

There is a logo archive download that gives you 1000s of amazing logos. It is hard to find a team name that does not have lots of matching logos.
Credits to all the people that created them and made them available.
