"Oh! Now I remember where I put my wallet."
"Oh" here is the interjection among your examples.

Explanation:

An interjection is a word or expression that utters on its own and expresses a spontaneous feeling or reaction.

These includes exclamations (ouch!, wow!), curses (damn!), greetings (hey, bye), response particles (okay, oh!, huh?), and hesitation markers (uh, er, um).
