Only the College of Lore subclass is available for free, as part of the D&D Basic Rules. The College of Eloquence was published in Mythic Odysseys of Theros. You can purchase just the subclass itself at that link (scroll down to individual purchase options) for fairly cheap.
Edit: Doh you'd bought it. Okay, what you should do is bump your character up a level and then back down so that it refreshes feature data, including new purchases.
Hey,
I am unable to add College of Eloquence to my Bard college when making a character.
Anyone else having this issue?

yeah might need to contact the support team, says everything is sync but still can't see it. I tried your suggestion tho and nothing.
Oh, derp... you also need to turn on the Sources toggle for Magic: The Gathering content.
