Unfortunately, you can't import your previous taxes year's data from TurboTax Online to TurboTax Desktop. TurboTax Online can't export anything other than a PDF file, and TurboTax Desktop can't open PDF files. Only .ttxx files.
Because this will be your 1st year using TurboTax Desktop, you'll have to enter information manually, but with future years, you'll be able to import data from the .ttxx file saved on your computer.
Thank you for choosing TurboTax.
