I turned off ALL circuit breakers in the panel.

I then pulled out the duplex receptacle from the electrical box in my garage and removed the wires.

I then attached the black, white and ground wires to a new duplex receptacle with two USB ports.

I was shocked by another white electrical wire in the box. Why wasn't that circuit controlled by a circuit breaker in the panel? Should the white wire have power?

Sometimes two different energized circuits wind up sharing a neutral and that could be the reason you got a shock off the white neutral wire. o_O

Always wondered- what exactly is a "neutral" wire in an AC circuit?

The NEC is addressing that more in every cycle. In fact they want to
stop saying neutral altogether. It is the "grounded" conductor. (not
to be confused with the "grounding" conductor.
It is simply the terminal on the transformer that gets grounded. Other
than that the AC is still that sine wave you learned about in high
school. Current reverses direction through that circuit with a
complete cycle 60 times a second.
