If you're using QuickBooks Self-Employed (QBSE), you can have the Profit and Loss report and Tax summary report.
A profit and loss report summarizes your income and expenses. The Tax summary report will show your taxable business profit and totals for Schedule C and healthcare deductions. You can run this by going to the Reports tab on the left menu.
