Why do my credit card transactions often times don’t show up

Hello @CindyAB,

Thank you for posting here in the Community. I can provide some clarification about how the banking feature works in QuickBooks Self-Employed.

When you link your account, the transactions that will show up or download depends on your bank. Any banking data they share will be uploaded to the system automatically.

Also, your bank account should remain connected to avoid your transactions from disappearing. There are times that banking data won't show up.

In this case, I recommend updating the connection between QuickBooks and your bank account. You can do this by clicking the Refresh all option within the Banking section.

Here's how:

1. Log in to your QuickBooks Self-Employed (QBSE) account.
2. Click the Gear icon in the upper-right corner.
3. Select Bank accounts, then press Refresh all. 

For additional reference, I've attached a link you can use about how to download data from your bank's website, as well as the steps to upload it in QuickBooks: Add older transactions to QuickBooks Self-Employed.
