Hi there brokezakbagans-g,
It's vital that your transaction are correctly entered within your books so that they are accounted for. QuickBooks Sef-Employed is a great tool that is able to import transactions directly from your bank's site to save you time with entering data. I can provide some assistance with these missing transactions.
The cause for the transactions to not appear in your account could be browsing data in your system. Temporary files such as cache and cookies can affect your navigation in any online software such as QuickBooks Self-Employed. Here are some ways to resolve any issues caused by browsing data:
If the error still persists after trying those steps, I recommend reaching out to the QuickBooks Self-Employed support team. They'll be able to verify your account details to help you get those transactions to appear once again. You can reach out to them by navigating to the assistant feature and typing Talk To Human.
If you have any other questions, feel free to reach out here.
