As you have mentioned that you used TurboTax Online last year and will be using the TurboTax 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.
You can see last year's information by signing into TurboTax Online TY2023.
