After playing in five European Junior Curling Challenges Turmann finally qualified for the World Junior Curling Championships in 2015. Turmann would skip the Estonian team there, with teammates Kerli Zirk, Kerli Laidsaulu and Johanna Ehatamm. The team finished the event with a 2–7 round robin record, missing the playoffs. In her last year of junior eligibility, Turmann led Estonia to a fourth-place finish at the 2016 World Junior B Curling Championships.
