How do I get the 2017 and 2020 years Turbotax Premier when I no longer have the purchase confirmation?

I've resent the receipt for your tax year 2020 order. You should receive it shortly. 

Unfortunately, we are no longer able to access the receipts or codes for tax year 2017. If you still have access to your old computer, you can open TurboTax Desktop 2017, and select View > Summary > Return Counter Summary, then click on details to see your code.
