You can find the default Toneprint for your TC Electronic pedal in the Toneprint Editor application. 

The easiest way to do this is to search via Library and then look for the TC Electronic, All TonePrints by TC Electronic option. 

If you then select your pedal from the available list, you will then see a full list of compatible TonePrints for your device. 

Depending on what pedal you have will determine the name of the default TonePrint.
It will either be listed as "TonePrint 1, 2, 3" or as "(Pedal Name) Default".

Please see the following 2 images as an example of this. 

If you then transfer these TonePrints to you pedal you will have the default sounds.
