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.
