Please follow this guide for your reference: Manually add transactions in QuickBooks Self-Employed.

You'll want to exclude some entries so only those people who paid only show. It will be a combination of your personal and business transactions. When you link Venmo account, QuickBooks will automatically download all recent transactions or it depends on what Venmo allows to download. I can share information about downloading Venmo transactions in QuickBooks Self-Employed(QBSE).
