IMPORT QUICKEN TO ONLINE
You can NOT import Quicken or QuickBooks or .txf files to the Turbo Tax Online version any more at all.
IMPORT Q USING TXF
You CAN directly transfer Quicken into the Turbo Tax Windows Desktop program. If you need to transfer Quicken to Turbo Tax for Mac or to older Windows tax returns or from an older Quicken version you need to export your Quicken data as a txf file.
