For the calibration sketch to work you neet to init the screen and touch in portrait orientation

as per your code this defaults to landscape mode

  myGLCD.InitLCD();
  myTouch.InitTouch();

you need to change it to this

myGLCD.InitLCD(PORTRAIT);
myTouch.InitTouch(PORTRAIT);

once the calibration is done you can go back to landscape if you want

Start simple, have you tried the quickdraw example?

#include <UTFT.h>
#include <ITDB02_Touch.h>

UTFT myGLCD(ITDB32S,38,39,40,41);
ITDB02_Touch  myTouch(6,5,4,3,2);

void setup()
{
  myGLCD.InitLCD(PORTRAIT);
  myGLCD.clrScr();

  myTouch.InitTouch(PORTRAIT);
  myTouch.setPrecision(PREC_MEDIUM);
}

void loop()
{
    while (myTouch.dataAvailable() == true)
    {
      myTouch.read();
      myGLCD.drawPixel (myTouch.getX(), myTouch.getY());
    }
}
