What action did Ted take regarding his bank account?

Ted deposited money into his bank account, which means he added funds to it. Depositing money typically involves transferring money into an account with the intention of safely storing it and possibly allowing it to accrue interest over time. This action is often undertaken to increase the available balance in the account for future use, whether for personal expenses or savings purposes. By choosing to deposit money, Ted is ensuring that his funds are secure and accessible when needed, compared to spending or withdrawing, which would decrease his account balance.
