Hi there carol-groovyconc,
Thanks for reaching out about your credit card transactons. QuickBooks Online is a great tool able to connect to various banks to import transactions. I cna provide some information about entering transactions.
One way you could import this transaction to be reveiwed in the Banking tab would be to follow the steps in this article to import transactions. Please note if you use a file that has more than just this trnsaction, you would need to exclde the transactions that have already been imported, as to not have duplicates in your books.
You can also create the transaction manually by clicking on the +New menu in QuickBooks Online, then selecting the type of transaction needed. Enter the information about the transaction, then Save.
If you have any other questions, feel free to reach out here.
