Can I issue a 1099 to a vendor using QuickBooks Self-Employed? I had big project and hired helpers.

Welcome back for more support, @erick_rene_herna. Thanks for clarifying the version of QuickBooks you're using.

The Workers tab is only available in QuickBooks Online (QBO) for small business owners. The steps above provided by my peer @MariaSoledadG are for QBO users who need to issue a 1099 to a vendor. To learn more about how to file taxes in QBSE, read through this topic: QuickBooks Self-Employed - Annual taxes guide. 

I've read your previous post and I've learned that you've hired helpers for your big project. You can switch to QBO version as a workaround. Below are the variety of QBO products that you can choose from:

• Use the QuickBooks Online (SimpleStart, Essentials, and Plus) plan if you're a small business owner that need to track expenses, create invoices, and run reports. For an additional fee, you can add on an Enhanced Payroll feature to any plan so you can pay and file forms for your employees and contractors.
• Use the QuickBooks Online Payroll stand-alone (Core, Premium, and Elite) plan if you'll only need basic payroll service. This will also let you pay and file W-2's for your employees and 1099's for your contractors. 

Here's an article that you can read through in case you need to switch from QBSE to QBO: Move your QuickBooks Self-Employed data to QuickBooks Online. It helps you learn about downloading and importing your data manually.
