user137587: I have some USDT in an exchange and I want to deposit it to another, I have 2 options of depositing to either an ERC20 or TRC20 addresses, does it matter to which I send it to? Will I lose my funds if I send it to the incorrect address?

user137501: Those addresses belong to other, non-Bitcoin blockchains. ERC20 is the Ethereum blockchain, and TRC20 is the Tron blockchain.

Will I lose my funds if I send it to the incorrect address?

It is possible to lose your funds like this, so be very careful with the address - you must create an address for the particular blockchain where you wish to receive your USDT, and have a wallet that can receive and send assets on that blockchain.
Note that originally, USDT existed as a token on Omni Layer which is a protocol that uses the Bitcoin blockchain to record special transactions:

Omni is a platform for creating and trading custom digital assets and currencies. It is a software layer built on top of the most popular, most audited, most secure blockchain -- Bitcoin. Omni transactions are Bitcoin transactions that enable next-generation features on the Bitcoin Blockchain. Our reference implementation, Omni Core is an enhanced Bitcoin Core that provides all the features of Bitcoin as well as advanced Omni Layer features.

However, most exchanges don't support USDT-Omni, and I'm not sure if even the issuer (Tether) anymore mints/redeems USDT-Omni for USD. So, if you're using USDT it is most likely NOT on the Bitcoin blockchain.
