As of this time, QuickBooks Self-Employed does not support direct exporting of your 2018 self-employed taxes. You can download your Tax Detail Report and use it in manually recording your data to TurboTax.
Go to the Reports menu.
Locate the Tax Details report.
From the drop-down, choose 2018 tax year.
Click the Download button.
Once completed, you can log in to your TurboTax Self-employed account. You can read through this article to learn more about preparing your tax information in QuickBooks Self-Employed: QuickBooks Self-Employed annual tax guide.
