In a way that is not correct or accurate.
She answered the question incorrectly on the test.
Incorrectly → It is formed from "in-" (meaning not) and "correct" (from Latin "correctus", meaning to set right) and the suffix "-ly" (meaning in a manner). The word "incorrectly" means in a manner that is not correct or wrong.
Think of 'not' ('in-') and 'setting right' ('correct') to remember that 'incorrectly' means doing something in a wrong way.
