I appreciate the time you've given to check this with us today. I can share some insights about adding your bank transactions in QuickBooks Self-Employed.
QBSE is a cash-based system and is mainly used for tracking business income and expenses to estimate the taxes. It doesn't have Chart of Accounts, which is why we're unable to assign a specific account for your transactions or add another account.
The Cash Account in QBSE is the default account where your manually created or imported transactions are posted.
If you'd like to use a different account, you have the option to connect your bank into the program. This way, you always have up-to-date transactions. Let me show you how to do that:
Click the Gear icon then select Bank accounts.
Enter the name of your financial institution or website/URL in the Search field.
Select the right bank from the list of search results.
Key in your bank's username and password and click Connect securely.
