It isn't clear what you are wanting.
You said you typed in a long line and showed how it displayed on the LCD and then asked:
So may question is..how can I display it in the serial monitor like this:
my name is edgar
steven olazo
Which is asking how to change the output on the Serial monitor.
So I can't tell if you are wanting to change the Serial output or the LCD display output.
Wrapping long lines is easy, breaking a string and wrapping a line so that characters in words don't wrap across lines is much more difficult.
If all you need to do is wrap long lines on the LCD then you could switch to my hd44780 library.
It is available in the IDE library manager - use the hd44780_I2Cexp i/o class. More here:
You can control line wrapping on the LCD using lineWrap() and noLineWrap()
While that will wrap lines, it won't wrap on word boundaries. That is more difficult and would have to be done in your sketch code as the LCD library can't do it since it can only see 1 character at a time so can not see the entire string.
