I feel your pain! This may likely be the last year I use TurboTax there are many alternatives now that are just as good and less expensive.
I was also using Windows 10 Laptop with Turbo Tax Premier. One common thing I found with my situation was I used the Import option to get my previous year's information from my PDF file. Last year I did the Turbo Tax online version, not the desktop version. Therefore, I did not have the native .tax file.
Every time I used the import it resulted in the corrupted file.
I started from scratch and did not import any previous tax information and I was able to make it through and save and access my file after I closed it.
I'm very disappointed in Turbo Tax's response. I spend several hours starting over and over after entering data many times before I figured out how to avoid the problem. I requested help and ended up figuring it out myself. This does concern me that if they have such a problem, will my taxes actually be correct? What other mistakes did they make?
