MCUFRIEND_kbv library is for Parallel shields.
You have a SPI shield. You can download library from Waveshare Wiki page
Follow the Wiki. Run all the library examples.
If you have a problem, quote the example by name.
Calvin Hass and / or MHotchin are often on the Forum.

You want the 'Waveshare_ILI9486' library. It is available in the Arduino IDE library manager, or directly from here:
