Bludgeoning, piercing, and slashing damage have a distinction between B/P/S from a magical source, such as a magic Longsword, or a creature that has attacks that count as magical, but I do not recall a case where a distinction between Fire and magical fire damage has been made in 5e.

Even in 5e, Magical B/P/S is being phased somewhat phased out. Mord Presents Monsters of the Multiverse converted creatures that had magical B/P/S damage into Force Damage. Presumably, the Monster Manual 2024, will convert the rest of creature magical B/P/S into Force damage as well.

Magical Fire damage though…not RAW.
