  We construct the wave functions in the q-deformed 2d Yang-Mills theory that
compute torus correlation functions of affine currents in the VOA associated to
a class of 4d $N = 2$ SCFTs. These wave functions are then shown to reduce to
the topological correlators of a set of Coulomb branch operators in the
$T[SU(N)]$ theory, from which those correlators in the 3d mirror dual of the 4d
TN theories can be computed.
