Transfer from Trezor to coinbase

noob here… I set up my wallet and transferred my coins from coinbase into the wallet. What I didn’t know is coinbase transfers BTC as CBBTC (wrapped BTC), which is complete BS but…
It is my understanding that if I transfer them back to coinbase I can transfer them to my wallet as actual BTC by using a specific transfer process.
The BTC transferred via “Base#1” ( i don’t remember selecting this, I think CB did) as Tokens. When I attempt to “Send” the CBBTC back to CB it only provides the option to Send as currency/money ex USD

How do I transfer the CBBTC back to CB and ensure I’m keeping the BTC and not converting it to USD?

Thanks

The send form is for sending crypto only. You can enter the amount in the send form in units of either CBBTC or your preferred fiat currency (USD is selected by default). The send max button allows you to send the whole amount.

Please note that on the Base network, you need ETH to pay for gas (network transaction fees) when sending any transactions.

Once you receive the CBBTC back on Coinbase, please make sure you are sending it via the Bitcoin network using a Bitcoin address and not alternative address and network types like those existing on Base.
