Thanks for checking in with us, 5660.
May I know what data files are you trying to import? Have you encountered an error message? Any details you can provide can help us better isolate the issue.
In QuickBooks Desktop, we can import your data using CSV (comma-separated values) file and edit it with any text editor like Notepad. Once the data is imported, we can manually input them using the original dates.
To import a list in the CSV format, you need to install the QuickBooks Import Excel and CSV toolkit. Just follow the steps and details in this article: Import/export CSV files. Once done, try importing the files you need in your software.
