Turner was born in Bedford, Texas to parents David and Mary Turner, and started playing basketball as a six-year-old. He attended Central Junior High School, and as a 6-foot-2-inch freshman, he led his team to 27 wins.
Throughout high school, Turner played AAU basketball for the Texas Select team during the springs and summers to further develop himself and gain recognition as a player, participating in well known tournaments and camps such as the LeBron camp, the Nike Big Man Skills Academy, the NBPA Top 100 camp, Adidas Nations, and the Elite 24 invitational. Between his sophomore and junior year, Turner, then 6'7", broke his ankle during the first spring game of AAU play, hurting his chances of recruitment, but soon recovered and gained some 30 pounds through two-a-day weight training regimen to improve his game. In his junior year, after fully recovering, Turner averaged 15 points, 12 rebounds and eight blocks per game, leading Trinity to a 17–13 record and reaching the state playoffsfor the first time in 10 years, and only the ninth time in school history dating back to the school's establishment in 1968. He also accumulated six triple-doubles. During the 2013 AAU summer circuit, Turner maintained his high level of production, leading his Texas Select team to the title at the 2013 Jayhawk Invitational in front of coaches from most of the Big 12 schools. Going into his senior year, Turner began garnering nationwide attention and becoming a highly sought after recruit for his athleticism, ball handling, shooting ability, and natural shot blocking ability for someone of his height. He solidified that by finishing out his high school career with 18.1 points, 12.2 rebounds, 3.5 assists and 6.8 blocks per game, leading the Trojans to a 24–7 record. After finishing off his senior year, Turner was one of the last highly sought after recruits left that were uncommitted. He was rated a five-star prospect by many sites including Rivals.com and several more college basketball analysts as well as being considered the No. 2 center in the nation behind Jahlil Okafor. Originally going into his senior year in fall of 2013, Turner had already accumulated 60 various offers, but by his senior year, the list was narrowed down to Texas, Kansas, Duke, Arizona, Kentucky, Ohio State and Oklahoma State. On April 30, 2014, live on ESPNU's Recruiting Insider, Turner formally announced his commitment to play basketball for the University of Texas. Turner took part in the 2014 McDonald's All-American Boys Game, in which he recorded seven points and seven rebounds. He also represented the United States in the 2014 FIBA Americas Under-18 Championship, helping the country win a gold medal.
