Thank you for your quick reply.

The PDFs are the the finished tax forms -from what I can see-  what I need to access is the actually workpages of my previous years, where I would have filled out all the information.   I entered the names and amounts of deductions that were not claimed that year.    It should be saved somewhere.   Any ideas?

You can login to the previous years and open the returns. The donation section will have any receipts you entered.

Can you help point me in the right direction so I can access these? I am simply not finding how to access these.  I am only seeing the finished PDFs

You can go to the TurboTax site for the year that you are looking for.

Once you are in, open your return, then use the Find/Search bar to look for "don". That will bring you to the Donations section, where you can continue through until you get to the receipts that you've entered for the year, as well as the summary page which shows you how much is being claimed.

Ok thank you, that helped, but I still don't see the actual list that is "carried forward".
How do I do the same for 2020, 2019 ect.

Thanks for your patience,  this is pretty stressing  😕

Unfortunately, there is no list of which receipts have been carried forward. Only the dollar amounts are preserved. 

TurboTax Online is no longer available for years before 2022, as we typically only have 3 years available at a time.
