Hey there, @dpfrey66.

Yes, Self Employed (QBSE) does have a default cash account. Once you manually enter your transactions, the program will automatically create and add them to this account.

Thus, there's no need for you to worry since what you've done is correct. 

You can also read this article about adding transactions in QuickBooks Self-Employed. It'll walk you through the steps on how to track your income and expenses.

Get back to me anytime if you have any more questions with regards to managing your transactions in QBSE. I'll be happy to help.
