Unfortunately, you can't import or open TurboTax Online returns in TurboTax CD/Download. TurboTax Online can't create .tt files, which is what TurboTax CD/Download uses.
You can still print or download a PDF copy of your TurboTax Online return. Please see this TurboTax FAQ for instructions: In the online edition of TurboTax, how do I print a copy of my tax return?
Or you can use TurboTax Online again this year. If you use the same account as in previous years, then you will be asked if you want to transfer your information when you start your return.
If you need a refund, please use the form on this FAQ to request one: How do I get a refund for a TurboTax product?
FYI: For 2021, there is no Standard version of TurboTax Online. Instead, we have Deluxe. You can read more about on this TurboTax FAQ: What happened to the Standard edition of TurboTax Online?
