It appears it was a SegWit address since the deposit address was not generated under a legacy account. So it appears unless someone sets up a service to recover these mistakes I'm out of luck. 

Trezor 1.5.2
I used a BTC deposit address from my Trezor to withdraw BCH from viaBTC.  Since the BTC deposit address used was from my Trezor I should have access to the private key if that makes a difference. Is there anything I can do to recover my BCH?
The incorrect deposit address was 3KeeW491axa9dLAJ5SzPMZ9sPQSyG7UCCa
I tried to google this for an answer but didn't find much.

Thanks in advance.
