Turner missed some training sessions as he was organising his move from Sunderland.
"I'm not far away now in terms of fitness," he told EDP.
"It did take it out of me going to Korea and then coming back and coming straight to Norwich, and taking a few days for the deal to be done, so I'm pleased now I'm back in training and getting games and back on it.
"It's the best way to get your fitness up, playing games of football, being out there on the pitch.
"I was feeling stronger and stronger as the game went on."
