The American has slotted straight into Mick McCarthy's side, upon his second loan spell of the season.
Carter-Vickers was on loan at Sheffield United earlier in the season, making 17 starts for the Blades.
He lost his place in December and Spurs recalled him, before agreeing a loan with Ipswich.
Commenting on the change, Carter-Vickers has admitted he was stunned his spell at Bramall Lane came to an end.
Quoted by TWTD, Carter-Vickers said: "I was a little bit surprised when they said my loan was ending.
"Obviously, I was prepared to be there for the rest of the season so when I heard I was going back it came as a bit of a shock, but I’m delighted to be here.
“It all happened quite quickly but I’m happy with how things have worked out. I’m still in the Championship and playing regularly."
Tottenham should be happy with the progress Carter-Vickers has made this season. 2017/18 is the first year he has been out on loan and he needed it after getting close to the Spurs first team but not quite breaking through.
He is picking up valuable experience and if his time at Sheffield United was going to mean more bench time in the second half of the season, Tottenham were right to pull the plug and find him a new club.
Assessing his time at Bramall Lane, Carter-Vickers said he will remember it well.
He said: "I found it helped my development. I left there a better player than when I went and I’m very grateful to them for the coaching I received.
“It definitely helped me to improve as a player and it was a very positive experience for me."
Carter-Vickers will take on Sheffield United on March 3 at Portman Road when the two clubs next meet.
