Getting Error 102348 when trying to save or save as to Hard drive.

The note from herbb623tt about Ransomware Protection in Windows 10 Windows Defender anti-virus settings also worked for me. 

I had an option to simply add an exception rather than disabling the entire feature … "Add an app through Controlled folder access". I browsed to the location of the TT executable file. I had to exit and restart TurboTax.  Before doing this I was able to save my in-progress tax return to a USB drive. After starting TT I was then able to read the return off the flash drive and re-save it to my hard drive.

TT location on my pc: C:\Program Files (x86)\TurboTax\Deluxe 2018

I think I found the answer.   If your using Windows 10 Anti virus, there is an option called Ransomware Protection.  That was turned on.  Turning it off allows me to save files to the hard drive. Apparently Windows 10 doesnt fully trust TurboTax.  : - )  

To correct error 102348:

1. Go to Windows Settings and Click on Update & Security

2. Click Windows Security

3. Click Virus & Threat Protection

4. Virus & Threat protection settings / Manage Settings

5. Controlled folder access / Manage controlled folder access

6. Allow an app through Controlled Folder Access

7. Do you want to allow Windows Security to make changes to your device?--YES

8. Click Add an allowed app

9. Enter TurboTax

This should allow you to save TurboTax to your hard drive.

How to fix?

The actual solution on Windows 10 is to Go to Windows Security, Virus & Threat Protection, Allow an App through Controlled folder access, choose recently blocked apps then Turbotax for current year.
