how can I read this button press?

#include <XPT2046_Touchscreen.h>
#include <SPI.h>

#define CS_PIN  PB6


XPT2046_Touchscreen ts(CS_PIN);

void setup() {
  Serial.begin(38400);
  ts.begin();
  ts.setRotation(1);
  while (!Serial && (millis() <= 1000));
}

void loop() {
  if (ts.touched()) {
    TS_Point p = ts.getPoint();
    Serial.print("Pressure = ");
    Serial.print(p.z);
    Serial.print(", x = ");
    Serial.print(p.x);
    Serial.print(", y = ");
    Serial.print(p.y);
    delay(30);
    Serial.println();
  }
}

if ((p.x>1350) && (p.x<2020) && (p.y>340) && (p.y<1200)) {
  // do stuff
}

makes sure that the point is within the bounds of the button, now all you need to do is include the p.z value bounds
