Go on. There is a standard graphicstest example sketch.

All that you have to do is say whether you have altered it.

If you have, simply copy-paste your altered lines e.g.

// These are 'flexible' lines that can be changed
#define TFT_CS 10
#define TFT_DC 9
#define TFT_RST 8 // RST can be set to -1 if you tie it to Arduino's reset

and which constructor you used

// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ST7796S_kbv tft = Adafruit_ST7796S_kbv(TFT_CS, TFT_DC, TFT_RST);
