It's good to see you around, KD71! I'm glad that even at your age, you still use QuickBooks for your business.
QuickBooks Desktop is a double-entry bookkeeping program and has registers while the QuickBooks Self-Employed is not and it has no registers. For these reasons, we're unable to do an integration with these programs.
If you'd like to load up your transactions into QuickBooks Desktop, you can connect your bank account to download them. Or, you can download them from your bank in a Web Connect file (.QBO format) and upload them to QuickBooks. Here's an article with steps to upload your bank transactions: Import web connect (.qbo) files.
