Finally got it figured out. Once I got the computer to open the FoxPro app I downloaded, it ended up being incredibly easy loading the sounds I bought onto my X1 call. I was even able to easily create a "TT Sounds" category so the new sounds are easy to find on the remote. Seemed a lot easier than I remember on my Fury2.
One thing worth mentioning when updating the call list on your remote, you must follow the sequence or it will not work. Turn on remote, hook up cable to remote, then follow what the remote says. I initially had everything hooked up and on and it would not work.
