Hi there,
I know how essential it is for you to be able to add your receipts to your banking transactions. Doing this helps you stay organized, and having a digital copy of receipts is a great way to ditch the shoebox full of paper! I'd be happy to explain the next steps so you can get back to business.
Since you're using the Self-Employed product, please reach out to their designated support team here: Contact QuickBooks Self-Employed. I'm confident this team will be able to help you reach your goals in no time.
You can also reach out to them in-product to chat by following the steps here: In-App Chat Support - QuickBooks Self-Employed.
I hope this helps.
Have a great day.
