A brief review of the available experimental and theoretical results on production $\chi_{Q1}$ states in $e^+e^-$ annihilation photon-photon $\gamma\gamma^*$ interactions is presented. Future data $\chi_{c1}(1P)$, $\chi_{c1}(3872)$, $\chi_{c1} (4140)$, $\chi_{c1}(4274)$, $\chi_{c1}(4685)$, $\chi_{b1} (1P)$, $\chi_{b1}(2P )$, $\chi_{b1}(3P)$ resonances will help development unification predictions related to electroweak decays heavy quarkonia, reduction their spread model uncertainties.
