I created an offline wallet in Coinbase. I have some Ethereum coins in the account. I printed the document and kept it with me. There are six sections on the document:

MyVault Vault backup                 Recovery Instructions

Shared key                                Shared key wallet recovery

Coinbase key                             General Information

My question is, if I wanted to sell my coins and bring the money to my bank's account, what would be the process?

Really appreciate anyone who answers.
