You can only import Quicken directly into the Turbo Tax Windows Desktop program and not to the Online version. If you need to transfer Quicken to Turbo Tax for Mac or to older Windows tax returns you need to export your Quicken data as a txf file. (Neither TurboTax Online nor TurboTax Business supports imports from the .txf file.)
