Two-weapon fighting rules, per the Player's Handbook (page 195):

When you take the Attack action and attack with a light melee weapon that you're holding in one hand, you can use a bonus action to attack with a different light melee weapon that you're holding in the other hand. You don't add your ability modifier to the damage of the bonus attack, unless that modifier is negative.

Per my earlier question, I am allowed to use different weapons for an Attack action if I have the Extra Attack class feature. Let's assume I did just that, attacking once each with a hand-axe and once with a shortsword. Am I allowed to afterwards perform a Two Weapon Fighting bonus attack with one of these weapons?
