Did you click on the "Sign" button? If not, that's the first step.

Go to Ian Coleman's BIP39 converter[1] (or run it locally (https://github.com/iancoleman/bip39)) and write your recovery seed in the "BIP39 Mnemonic" field. Then, scroll down to the "Derived Addresses" section and try to find your address (13ZjqoaMNQSWxXwejA7t5iAWYLcuahE1mi) there. If you do, copy its private-key and import into Electrum (File -> New/Restore -> Import Bitcoin addresses or private keys -> Paste your private key -> Next). Then, try to spend the coins (you won't need the Trezor).

P.S: This will make your current wallet unsafe since the private-keys aren't isolated in the device anymore. When you recover your coins, create a brand new wallet (with a new seed) and try again (this time, test receiving and sending with a small amount before sending your whole balance).

Do you remember which derivation path you choose when setting up your Electrum (connected with the Trezor)? In this step to be exactly:

That's weird... Your addresses should start with a "3" and not "1". Are you sure that you used this exact derivation path?

m/49'/0'/0'

Including each one of the apostrophes.

If you create a new Electrum wallet with the same steps (Standard Wallet -> Use a hardware device -> Select "Trezor" -> Put the m/49'/0'/0' derivation path), do you get the same wallet with your 52 mBTC? And if you go to the "Addresses" tab (View -> Show Addresses, if the tab is disabled), do you see addresses starting with a 1 or 3?



Edit: helped OP via Skype. His issue was that when creating his wallet, he chose the legacy (p2pkh) type while changing the derivation path to m/49'/0'/0' (used on p2sh-segwit/p2wpkh-p2sh), which doesn't seem to be supported by Trezor. The solution was to use his backup seed to restore his wallet on Electrum with the same config, which was supported by Electrum.

@OP: Note that after this step, your seed should be assumed to be compromised.
In order to keep the seed of a hardware wallet truly offline and isolated, you need to create a new seed with your trezor.

Forgot to mention it here that but I certainly told him to do that. The last time he was seen online (on BTT) was on August 26, so...
