The German coach insisted the extra day's work was not served as a punishment and dismissed suggestions of a fallout with Marcos Alonso.
The pair were seen rowing during the Wolves clash and at half-time, the Spanish defender was substituted as Chelsea changed their formation.
Asked about any issues with Alonso, Tuchel - who has just one win in his last five league games - replied: "It started and ended in the first half, and was not continued at half-time or anything else.
"It was not continued at half-time, things are solved, and that happens.
"We came in on Sunday, we'd planned a free day but after the disappointment it was not even to punish them.
"It was normally a free day and of course maybe some felt it was a punishment but it wasn't.
"It's not the moment for a free day, I explained to them, it's better to be together and talk about it than to go, everybody has his own opinion and everybody has his own truth, maybe it's more risk to be in fragments than in here.
"So we did here very, very light training, just had a run together and spent time together discussing things, how we want to approach the next days.
"That was actually why we brought everybody together, to have the chance to be together, then a lot of players supported the under-23s on the other pitch.
"It was very nice to see and actually it was what we are, a very supportive and open-minded group of players.
"So that's what it felt like on Sunday, that was the Sunday morning.
"It was not to punish them, not do to a video session and show mistakes, it was just to be together and actually not to be in different groups and be away from each other on a free day. That's why we had everybody in."

Tuchel admitted Chelsea's draining season continues to take a toll on his players, with the weekend's FA Cup final against Liverpool moving ever closer into view.
"We look a bit drained, tired mentally; we look at the sideline, this is understandable given the circumstances around the club in which we play in," said Tuchel.
"This is draining, this is challenging. We had some knockout games in which we play after the national break, with huge emotional input, huge emotions to deal with.
"From losing to Real Madrid, winning at Real Madrid, losing the Champions League then suddenly being at Wembley and then suddenly in the race in two weeks with four matches against different teams in the Premier League.
"It is quite challenging. After all we have a lot of matches in our legs, in our bones.
"We feel it. It's another reason. I think everybody knows it, we can even feel it and still with being tired, distracted, maybe concerned, we need to reach a certain level which is possible.
"We can do better than we did in the last two matches. The positive thing is that I feel the will, the motivation.
"The motivation was very high to turn things around against Wolverhampton.
"You see the physical input, it was maybe too high in some situations where we even attacked with defenders, very high in the pitch and opened space in counter-attacks.
"It was not a lack of motivation, it was the opposite. There was good signs. We trust the team, we trust our players and trust what brought us here.
"Now is the moment for me to stay calm, take it step by step and finish the season on a positive note."
