Hello there, gma-malina.
When transactions are missing, it might be due to the following reasons:
- An update on your bank’s information such as the name (bank merger), account number and login credentials require you to refresh it in QuickBooks Self-Employed.
- Ongoing maintenance from your bank’s website.
Let's try to refresh your bank by going to the Gear > Bank accounts > Refresh all. Here's a sample screenshot for a visual reference:
If the transactions are not updated, then you can manually add them. Here's an article for the detailed instructions: Add older transactions to QuickBooks Self-Employed.
You can always get back to me if you have any additional questions or other concerns. Take care and stay safe!
