You don't have to worry about backing up your QuickBooks Self-Employed (QBSE) data onto a flash drive. This is because QBSE automatically backs up your data with the same level of security used by banks and financial institutions.
Meanwhile, you'll want to export your data say your transactions and trips from QuickBooks Self-Employed to Excel. Please read through this article for the detailed steps on how to achieve this: How do I export my transactions and trips in QBSE to Excel?
Moreover, you can explore the QuickBooks App Store to check for other third-party apps that might fasten the export process which also suits your business needs. Here is a direct link that you can use: https://quickbooks.intuit.com/app/apps/home/
