Ok. I got it, finally! What I ended up doing is clicking the eyeball on the bottom layer to make it invisible, and painting with black on the dup layer. that erased the pixels and left the transparent background. Then I made the bottom layer visible, and nudged the bottom layerto the top left until the hole filled in with the sweater texture. One key was using paint strokes that matched the direction of the sweater weave and leave parts unpainted in a random way. I left a little shadow to (try) to make it look natural. I noticed that I picked up a little texture in the bottom right that I didn't mean to, but it was a good learning experience nonetheless about masks, and I am generally happy with it, especially considering the original raw image.
I notice that if you really take the time to work on things yourself and then ask questions, the people on this forum are fantastic in helping. I have learned so much here. Thanks!
On this picture I actually did capture sharpening using an edge mask and unsharp mask, then did the touch up work, then cropped, then output sharpened. Here's the original and the final:
