You're supposed to use the initial 50 of Eva's currency to activate the tonic bottle she gives you. That will unlock the first bounty (clear 7 levels of verdant forest). Once you complete that bounty, you will unlock the rest of her bounties. Once you complete a full run of the verdant forest, you'll get the gift from Eververse.
Now, since you bought a package, you might not have the 50 of Eva's currency to use the tonic. Just go do some public events/strikes (i'm pretty sure Crucible will give it to you as well, but i'm not a PVP guy, so i didn't originally include it) til you get back to 50. Then use the tonic and enter the forest.
