You need to enable the TWT BEP20, so that it will show your TWTs. Try to follow this guide: How to Add or Remove a Coin
Also, please be informed that BEP20 is different with ERC20. BEP20 is a token on the Binance Smart Chain, while ERC20 runs in the Ethereum network. Some platform/services do not support Binance Smart Chain (BSC), so be careful in sending cryptos.
Oh, so you are using an ERC20 only wallet? You can get the private key (Backup your Recovery Phrase or Private Key) then import it as a Smart Chain wallet. So you can access the TWT BEP20.
