She last played for the NT in 2021 at the Tokyo Olympics. She is already 36, so i think she is as good as retired now that Russia will not be back to international competitions in the near future.
This is Kosheleva's generation, so she will naturally leave volleyball anyway. After finishing her career, Kosheleva got a job with the youth sector in Vallefoglia. It's good that Italian clubs reach out to such people from other country, because you can't just close yourself to your own school. On the other hand, Kosheleva herself seems happy in Italy and intends to move there permanently.
