I take it you mean Enom when you say channelme.tv?
Log into your enom account, choose the name you want to transfer, click on EDIT CONTACT INFORMATION. Scroll down the page and at the bottom you will see EMAIL AUTHORIZATION KEY TO REGISTRANT. Click on this and you will be sent the key via email.
I do not know if once the domain is in your Godaddy account that a Channelme site (if there is one) will migrate with it, as you have to pay a fee at Godaddy for this service.
