The longtime Los Angeles Dodger signed with the Red Sox for one year and $21.7 million last month.
The deal includes a player option for the 2024 season.
The 38-year-old hit .278 with 13 home runs and 81 RBI in his final season with the Dodgers.
Turner was a key factor in the Dodgers reaching the World Series three out of four years from 2017-20, and won a ring with the team during the COVID-shortened season.
On Twitter, Bob Nightengale of USA Today was the first to provide the update on Turner’s deal with the Red Sox.
The Boston #RedSox officially announce infielder Justin Turner's $21.7 million contract (one year and a player option).

Boston’s offseason has very much been a mixed bag thus far.
The team has been productive, having signed Turner, Masataka Yoshida, Kenley Jansen, and Corey Kluber.
But they failed to retain Xander Bogaerts and were barely outbid on Jose Abreu, Zach Eflin, and Tommy Kahnle.
They also lost J.D. Martinez.
But with the addition of Turner, they have somebody to fill the hole left by Martinez’s departure, somebody who can serve as a designated hitter and play multiple positions in the infield if need be.
Turner and Jansen were teammates in Los Angeles from 2014-21.
The Red Sox finished 78-84 and came in last place in the American League East on the heels of a surprise run to the ALCS in 2021.
But Turner brings a veteran bat to their lineup who possesses power and can hit in the middle of the team’s lineup.
