Kovács played her first regular season in the Riksserien (renamed SDHL in 2016) in 2012, as a 17-year-old, with AIK Hockey. The following year, she claimed the starting job as the club won the SDHL championship.[1] She was named Best Goaltender of the Riksserien for the 2015–16 season.
In January 2020, Kovács announced that she was leaving Luleå and joining HC Örnen in the men's Hockeyettan as they competed for promotion to HockeyAllsvenskan.[4][5] She did not play during the following season, as she was pregnant with her second child.
Kovács made her return to the SDHL for the 2021–22 season, announcing a one-year contract with AIK in April 2021.[6]
She officially retired after the 2021–22 season, explaining that trying to balance playing elite ice hockey and caring for her two young children wasn’t sustainable in a healthy way, particularly since she could not make a living as a player.[7]
After sitting out the 2022–23 regular season, Kovács joined the women's team of Lausanne HC in the SWHL B playoffs and chose to continue with the team in the 2023–24 season.[8][9]
