The working group decided to "postpone the Fifa Under-20 Women's World Cup Panama/Costa Rica 2020 - originally scheduled for August/September 2020 - and the Fifa Under-17 Women's World Cup India 2020 - originally scheduled for November 2020."
"New dates will be identified," Fifa said in a statement.
The working group includes the Fifa administration and Secretary Generals and top executives from all confederations. It unanimously approved a series of recommendations following its first meeting, which was organised via conference late on Friday.
While the tournament itself is five months away but just a few qualifying events have been held so far and the remaining have not been held due to the global health crisis which has affected more than a million people.
Over 50,000 deaths have been caused by the deadly outbreak so far.
