The winger has been linked with a move to Newcastle United in recent months in the British press.
With his contract running out in the summer of 2024, it is now a crucial point in the 26-year-old's time with Leeds.
Speaking at the Whites' Spanish training camp, Harrison mentioned his future.
"I enjoy being here at the club, I love being here," he told Leeds-Live.
"I've been here a long time now and I'm almost part of the furniture here now.
"It's a great place to be, I'm happy to be here and I think my agent is coming over in the next month to sort something out with Victor (Orta). So we'll see what happens."
