I had same problem and someone posted this solution that worked for me. Person said it was issue with Windows 10. To work around: Go to settings. Select Update and Security. Select Windows Security in left hand column. Go to Virus and Threat Protection Settings and under that heading select "manage settings." Go to Controlled Folder Access and turn it off.
After I did that, I could then save. You hopefully will be able to save your Turbo Tax file under"
C:\Users\yourname\documents\TurboTax\2019 your info
I made a note to turn Controlled Folder Access back on after I finished return. Hope it works for you! Fran
