I can't seem to find where my account is linked to accept payments. I was paid through an invoice I sent out from QB Self Employed but I can't find it.

Just to clarify, are you using QuickBooks Payments to accept payments online to your customers? If so, it's possible that you link your account to QuickBooks Payments. To verify, you can log in to your QuickBooks Payments account.

However, if you're not using QuickBooks Payments, you'll want to ask your customer where they send the payment.
