"If the fix is bending the key, how could it get so far out of adjustment? Is there another adjustment for this key?"
There are no adjustments for this (nor any other key!) on piccolo.
All of the many adjustments are made by location of pads within cups, bending, or thickness of corks. (BTW the last is not the way Yamaha does it - nor me.)
The adjustment in the case of your E key, is made by bending the stop with the cork on it, at the same time ensuring that the key cup arm is not bent at all in the process. (That would put several other adjustments out)
If you want to enjoy playing this piccolo, the sooner it sees a technician the better. Tiny leaks really muck up a piccolo's response.
