Hi LisaW62, can you clarify the "checkbox at the bottom of the review receipts window"?
Additionally, if you could provide a screenshot of the area you're referring to, it would greatly help in clarifying your concern.
Moreover, here's an article you can use to review and categorize your bills and receipt. Please proceed to step 3: Email receipts and bills to QuickBooks Online.
Looking forward to your response. Feel free to ask any other questions; we're here to help.
