  1. Connect a jumper from the TX pin (1 on the Uno) to the RX pin (0 on the Uno)

How about:

  1. Connect a jumper from the TX pin (Pin 1) to the RX pin (Pin 0)

Or:
4. Connect a jumper from the TX pin (Shield pin 1) to the RX pin (Shield pin 0)
Or:
4. Connect a jumper from the TX pin (Arduino Pin 1) to the RX pin (Arduino Pin 0)
