Welcome MattQ
Congrats on your new feathery friend

.
If he hasn't been doing the "step up" command maybe he hasn't been taught yet. I taught mine by gently pressing my finger just above the legs so that they had to step onto me. While doing this I said "step up" and when they did I gave them a treat.

It won't take long especially when food is involved lol I found that mornings are good for doing this as they were quite hungry and were easier to teach to get the reward food.
You are lucky that he is tame, makes life so much easier.
Just be gentle and let the bird work at his own pace. If you try to rush things it could have a reverse effect. I have found from personal experience that they work very well with favourite treats, and I only give them that treat at "training & performing time" as rewards. So they are more likely to do what you ask of them.
As an example I was looking after a bird for someone who had to go away for a week. She was having trouble getting the bird to come to her (bird was not clipped) and go back into it's cage. I found her fav food was capsicum.

So I loaded myself up with heaps of capsicum and called her. Only took a minute or two for her to realize what I had. Followed me around the house looking for the reward. I used the same method to put her back into her cage.
Is his wings clipped? Some people like to have their birds wings clipped to make them more dependent on them or to prevent escaping. It's a personal choice.
Sounds like he has decided you are his friend.

Just remember to always positively reinforce any good behaviour no matter how small. They have a great memory so if you hurt him he will remember it and hold it against you lol.
He sounds young so he may not have gone through his "bluffing" stage yet. There is plenty of info on here about that "fun" time lol
Good luck and enjoy your new found friend.
