This worked for me. You have to remap the NAS or network drive inside of TurboTax even though it shows it is already mapped. File, Open, Right-click on your network icon, select map network drive, select the drive from the drop-down menu (it will show as mapped), continue to remap it, it will force you to enter the password. Make sure to select "Reconnect at sign-in". This worked on both Turbotax Personal version and Business. The drive should map and open to see the files. Drive was visible after I closed and reopened the program.

I confirm that it worked for me. My network drive is usually p:\ . Inside TurboTax I open a file (for last year). I used the network root (//......) and mapped the usual drive to a spare letter (R:\). I found that when it worked I then could disconnect R:\ and p:\ continued to work over after I closed and reopened the program. So it seems to be a one-time thing.
No idea why this happens.
