I have the starter kit with the Arduino Uno, and I wanted to use the LCD display, but a circut board is plugged in on its backside, so I can't put the LCD in the breadboard, and I can't get them apart and don't want to break it..
It's the I2C backpack. Don't remove it, it makes the display much easier to use because the I2C interface uses less pins. Good LCD libraries support it directly.
Use the hd44780 library for your LCD. It will make using the I2C LCD much easier than other libraries. The hd44780 library is available via the IDE library manager.
