Trezor doesn't charge ANY fees to receive. That isn't how crypto works. Only the sending side (like your exchange) charges you … and it tells you the fee before you send.
Trezor simply shows what is on the public blockchain from the transaction generated by the sending side. If you looked up your transaction on the blockchain explorer, you would see exactly the same thing.
Also, Trezor doesn't charge anything to send. You will pay miner/network fees, yes, but Trezor collects none of that.
