I figured out how to get a receipt/invoice for Turbo Tax.
Go to your account:
https://accounts.intuit.com/app/account-manager/overview
(or you can get there by clicking the icon on the upper right of the web site)
in the left bar, select Products & Billing
Then select TurboTax
Then select Payments
You should see a list. Click on the "..." then "view details" to get a receipt.
Press "print" to print or save it as a PDF.
Good luck!
