When an electron is emitted from an excited atom, where exactly does the electron originate from, the energy levels or the electron itself, and at what time does it get emitted during the transition of the electron?

Well, it's a quantum phenomenon so there's going to be some weirdness. But basically the emitted electron is the same particle that previously was bound to the atom's nucleus. Freed by sufficient energy to overcome its binding potential, it now leaves behind an ionized atom carrying a positive charge. The timing question is harder and probably involves calculations of probabilities using quantum mechanics.

You are mixing things up. There is no such thing as an electron and an energy level. The electron sometimes behaves as a wave, sometimes as a particle. To accept the fact that is both helps a bit to get the paradoxes solved.
