where can we edit QBO's default option choices in Bank Transactions transaction type. I wish to reorder the offered order.

QuickBooks Online doesn’t allow users to reorder or customize the default choices in the Transaction Type dropdown. The list order and the default option are built into the product and can’t be changed.

If you want to save time, you can utilize Bank Rules to automatically set the transaction type and other fields for transactions matching your criteria, so you don’t have to adjust defaults manually.
