I'm not aware of any list, but you've probably covered the majority of the map while looking for Korok seeds, so maybe try looking for potential points of interest where you didn't find Korok seeds?
You should be missing six locations if that helps (every location is worth 0.08%).
Side quests themselves don't count towards the completion percentage, but may lead you to additional hidden places, so you might want to double check them just in case... some are easy to miss, and not all lists online are complete.
Kass's riddles as well... they're not all counted as quests, so you might want to check for them as well (he can be found in Rito Village if you've done them all... if not you can find a list of his locations in his diary on Washa's Bluff).
