I see lot of places where we put do, when I think it is correct without do.
Is there any difference between "I do have a pen" and "I have a pen"?

Usually, just "I have a pen" works. (It is always grammatically correct.)
You might want to use "I do have a pen" if someone asks, and you have to check before answering. Then, "do" would be stressed.
