Bard Spell List Aid

Is Aid on the Bard spell list?  I see it listed for Bards in other places but I do not see it listed here on D&D Beyond?

The spell description (https://www.dndbeyond.com/spells/aid) does not list as it being available to Bards, but there is an optional rule from Xanathar's(?) which provides additional spells to Bards, and Aid is on this additional list (https://www.dndbeyond.com/classes/bard#OptionalClassFeatures)

Thank you, but, I found the reference in Tasha's.  They actually add 15 spells there to the Bard's list overall levels.

 Yeah, the optional expanded spell list features are from TCoE.
