There are two possibilities:
- You sent the coins to the wrong address
- You are checking the incorrect path
If you want you can download xBull Wallet (it's an extension wallet) from the chrome store and connect your Trezor (read the documentation here).
When you connect it to a Trezor, the wallet by default will show you the first 4 account in your wallet, if you click in
Load more accounts it will show you 4 more.
If none of these is your account it means you sent the coins to the wrong account
NOTE: Also, remember that you can use a passphrase with you Trezor so make sure you are using the correct one
