adding cname records

adding cname records

Hi..
I tried adding cname records and txt records (one after another, not two at a time) with TTL 600 seconds on GoDaddy, I tried after 3 hour to verify the ownership of the domain. but it is giving me an error. my doubt is, 1. I have my domain name at GoDaddy, hosting at inmotion hosting and in middle CloudFlare is there.
Now where should I add the cname record, is it at godaddy or inmotion hosting and 2. also to mx records?

And Finally, should I delete this default mx records inorder zoho to work.


Thanks :)
