This is a "MICROSOFT" default setting that has absolutely nothing to do with TurboTax. You need to make some changes in Controlled Folder Access.
Click the start button and above that button click the settings icon, which is the little gear wheel, to open the settings applet.
Scroll to the bottom and click the Update & security applet.
On the left, select Windows Security
Under “Protection Areas” click Virus and threat protection.
Under “Virus & Threat Protection Settings” click Manage Settings.
Scroll down to “Controlled Folder Access” and select Manage Controlled Folder Access
If necessary, turn ON controlled folder access. Then under that switch select “Allow an app through controlled folder access.”
Click Add An Allowed App, then select Recently blocked apps.
Now select TurboTax 2021 and work your way out of everything back to the desktop.
That should do it.
