I'll ensure your credit card transactions will be added to your QuickBooks Self-Employed (QBSE) without delay. This way, you can categorize them anytime.
Before digging in, may I ask your credit card name? This way, I can check our reports to see if we have an ongoing issue. By doing that, I can provide you with a permanent solution to help fix the problem.
Make sure that your credit card account is linked to your QuickBooks Self-Employed. If they still need to be connected, I suggest doing it. So, the most current charges on your credit card will automatically be added to your account. For more details, see this article: Connect bank and credit card accounts to QuickBooks Self-Employed.
However, if your account is already connected to QuickBooks Self-Employed, let's manually refresh the connection.
Here's how:
Go to the Gear icon on the upper right side.
Choose Manage accounts.
Click the Refresh all button.
If the issue persists, I'd suggest manually importing your bank transactions using a CSV file.
Go as follows:
Go to the Gear icon and select Import transactions.
Click the Import older transactions hyperlink.
Hit Browse and pick your CSV file.
Match the details and follow the on-screen instructions.
