Same situation here. I used to be able to update return with QuickBooks data even though the files are on a shared drive, but for some reason i cant reach that drive this year as it wont show shared drives.
I don't have to time to be moving files to a local drive each time to update return with quickbooks data.

Too much risk of us doing that and working in the wrong file, not moving it back, etc.

It's a network program it should have no problems reaching a network location.
