What version of TurboTax did you use last year? And which version are you using this year?
If you used the online version last year and are using a desktop version this year, unfortunately, you can't import your previous tax 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
