Where can I find my invoice of Turbotax. I didn't receive by email, my email is correct. On products and billing, there is no link to the invoice.

Have you checked your spam/junk folder to see if the email went there?

You can also see the invoice by logging into TurboTax Online, opening your return and clicking "Payment Receipt" at the bottom left. You can print or screen capture it for your records if needed.
