The TurboTax tax data files only have a file extension of .taxYYYY, where YYYY is the year of the data file. Such as .tax2021 for tax year 2021. The full file name would be shown in this format in the Documents directory/TurboTax folder - 2021 Doe J Form 1040 Individual Tax Return.tax2021
PDF files would be in the format - 2021 Doe J Form 1040 Individual Tax Return_Records.pdf
An SCD file is a calendar file created by Microsoft Schedule+, a discontinued time management program that was part of Microsoft Office.
This file type has never been used by TurboTax.
I am using 2021 TurboTax Premier edition for Windows with the latest release and have no issues with the files in the TurboTax folder.
Current Version 021.000.0738 (click on Help at the top of the screen, click on About TurboTax, click Version)
Do a hard drive search, both physical, network and/or cloud for the data files using *.tax* Search parameters
