A .tax2021 file is the native format for turbotax. Do not import. Simply double click the .tax2021 file and your copy of Turbo should open it right up to allow you to do all the rest of the fun stuff. If wondering, open you Turbo file location after saving a turbo file and you will see it is saved as a .tax2021 file. Import is only for other (csv, txf, whatever) file formats. Clear as mud? If you have a .tax2021 file then that is a TurboTax file and double clicking it will open TurboTax 2021.....a .tax2020 file will open TurboTax 2020....see?
