Can confirm in 1.18.2 and 22w13a.

Code analysis (Mojang mappings, 22w13a): ThrownTrident extends AbstractArrow. In ThrownTrident#tick(), super.tick() is called, which is AbstractArrow#tick(). In this function, tickDespawn() is called when the entity has physics and is on the ground. In ThrownTrident#tickDespawn():

byte $$0 = this.entityData.get(ID_LOYALTY);
if (this.pickup != AbstractArrow.Pickup.ALLOWED || $$0 <= 0) {
        super.tickDespawn();
}

Again, in AbstractArrow#tickDespawn():

++this.life;
if (this.life >= 1200) {
        this.discard();
}

The entity is discarded when its life NBT reaches 1200 ticks (60 seconds).
