Hi aepage1,
Welcome to Community! QuickBooks Self-Employed provides multiple ways to record or attach expense receipts to your books. I'd be happy to provide some insight here!
You can use the Receipt Forwarding feature to email images of your receipts. If your transactions still appear to be missing, you may have created Bank Rules for which the transactions have been automatically categorized. Here's a helpful guide to assist you with manually adding the transactions, if necessary.
If you require additional assistance, please connect with the QuickBooks Self-Employed Support team.
Feel free to reach out with other questions. We'd be glad to help!
