Assuming you are referring to the Trust Wallet Token airdrop that Binance did in July 2020, there are a few steps you need to take in order to claim your tokens.
First, you need to make sure that you had Binance Coin (BNB) in your wallet on Binance.com on July 14, 2020 at 00:00:00 UTC.
If you did, then you should have automatically received an equal amount of TWT in your Trust Wallet on August 5, 2020. .
If you didn’t receive your TWT, or if you want to check to see if you are eligible for the airdrop, you can go to Binance’s support page and submit a ticket under the “Airdrop” category. You will need to provide your Binance account email address and Trust Wallet address so that they can investigate further.
At the time of writing this, it is not yet possible to trade TWT on Binance, but it is expected to be listed soon. Once it is listed, you will be able to withdraw your TWT from your Trust Wallet to Binance and trade it like any other cryptocurrency.
