Arduino IDE: Which board am I using?

I just acquired a SparkFun Inventor’s Kit v4.0. The instruction book has a copyright of 2017.
Following the directions to get started, the first step is to download the Arduino IDE. Which I’ve done. It’s version 2.3.6.

Next I plug in the board. The power light is on and the LED 13 is blinking. It’s plugged into a USB 3.0 port on my Windows 11 computer.

Now I have to tell the Arduino IDE board manager which board I’m using. And that’s where I’m stuck.

The instruction book says to select Arduino/Genuino UNO. However my options in the board manager (after searching for “uno”) are:

  • Arduino AVR Boards
  • Arduino megaAVR Boards
  • Arduino UNOR4 Boards

none of which say they include the Genuino Uno.

I tried installing the Arduino AVR Boards v1.8 which installed successfully however when I tried to upload I get
avrdude: ser_open(): can't open device "\\.\COM4": Access is denied.

I checked in Device Manager and COM4 is the USB Serial Port with a Driver provider of FTDI.

I’m new to the world of Arduinos so I’d really appreciate some help getting started! Many thanks in advance.

select: Arduino AVR Boards and then Arduino Uno
