QuickBooks for Mac data must be converted to Windows before it can be imported. Instructions
You'll need QuickBooks Administrator access.
QuickBooks should be installed on the same local drive as TurboTax (not networked) and should be registered.
The QuickBooks company file (.qbw filename extension) must be in single-user mode and should have been opened at least once on the computer you're using to import (no need to leave it open during the import).
Be sure to update your QuickBooks data before importing so that your books match your tax return.
If you already imported, you can re-import updated QuickBooks info by selecting Replace whenever prompted.
