Thank you for visiting the QuickBooks Community, Sherry!
QuickBooks Self-Employed (QBSE) will remember the items you've added to your transactions for future use. Currently, we're unable to remove them.
Please let me know if you have additional questions about items or transactions. You can also check out the references for QBSE on the QuickBooks Support page. Or, click on Help in the upper right-hand corner on your dashboard and search the topic you like.
