@Frankiemom and the lovely Frankie! I so love Orange-wings!!
That’s great he’ll step up away from the cage. Will he stay on your hand if you carry him to the cage and put him inside? I just had the idea of getting him used to being on your hand near or around the cage even if it’s traveling the other way!
I’ve written a couple of articles on how to train a parrot to step up which might be helpful:

I also have a fairly recently rehomed Orange-winged Amazon called JoeJoe. He too was reluctant to step up - from anywhere in his case. I have found that he adores head scratches and kind talking, so I use those to encourage him to step up. To get him to step up from inside his cage, I first give him head scratches through the bars, then open the door slowly and gently place my other hand near him, then lure him on with head scratches. Another reinforcer which might work for Frankie is a favourite treat!
Of course it may not matter that you can’t get him to step up from inside his cage - I usually just open the cage doors and everybirdie can climb out on their own.
They do make the cutest sounds, don’t they?
