Ways to tell them apart:
Overdo has to do with doing something to excess, whereas overdue indicates something is late.
Remember that overdo is about action and excess — do is part of the word.
Overdue is time-related; its about something being due' or late on a timeline.
If someone overdoes something, it can be tiring; do is action-oriented.
When a book is overdue in a library, it wasn't returned on time — related to time, not action.
