Create a New Checking Account

 

Create the account code for the register in Accounting>File>General Ledger>Chart of Accounts.

Accounting >File>Banking>New Register

The first transaction in a bank account needs to be a check as the system attaches other transactions to the check number before it for sequencing purposes.  If the first actual transaction is a transfer, write a dummy check to the register and then void it.

Only if the new register will be the DEFAULT register, you can set the default register here: Accounting>File>General Ledger>Standard Account Codes.
