How to start Dragonflight on a timewalking character that has already done war within

essentially as stated above. I leveled to 70 through the timewalking event then did a couple harbinger quests and popped into the dragonflight zone but never did any of the starting questline as far as I know. When I go to the dragon isles now it just gives me the quest to tyrhold to continue the campaign, am I locked out of doing it from the beginning. I don’t see wrathion in stormwind at all.
