I already e-filed through QB 2019 1099's. I need to reprint the 1096 form. How do I do so?

Welcome to the QuickBooks Community Space, @flaviolima2001.

You can follow the steps below to get a copy of your 1096 form.

1. From the left navigation pane, select Expenses.
2. Select Vendors, then click the Prepare 1099s button.
3. Provide the correct information for the tax year, then choose Print and mail.
4. Choose the  1096 form. 
5. If everything looks good, select Yes, looks good! Then select Print on a 1096 Form.
6. If the form needs to be aligned, select No, it doesn't line up and select Next. Then re-select the 1096 form.
7.  Click Print on a 1096 Form.
