Get your taxes done using TurboTax

I have used TurboTax for many years and never encountered any problems in bringing my taxes in from previous years.  However, this year it will not let me bring it over which means I have to reenter everything manually.  I purchased TurboTax Deluxe 2021.  When I went to begin, I specified import tax from previous year.  It did not show up so i specified import manually.  I have a Turbotax 2020 pdf file.  I get the following message each time I try.  

"This import was unsuccessful.

 

We recommend you check your internet connection and try again. If we still can't get your info, don't worry. We'll help you enter it manually so you can keep working on your taxes."

 

I have cleared my cache and my cookies but that did not help.  There is nothing wrong with my internet.  Can you tell me what to do?
