Unable to upload code to MEGA2560

I am new to Arduino and I am currently setting up a MEGA2560 with RFID module (RC522)

Whenever I try to upload the code I have, it displays the error message.

Arduino: 1.8.12 (Windows 10), Board: "Arduino Uno"

Sketch uses 9602 bytes (29%) of program storage space. Maximum is 32256 bytes.
Global variables use 295 bytes (14%) of dynamic memory, leaving 1753 bytes for local variables. Maximum is 2048 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

What should I do?

You seem to have the wrong board selected in the Tools menu.
