As of now, QuickBooks Online (QBO) doesn't directly support downloading EFW2 files, Raymundo. Let me share some information.

You can prepare the file manually outside of QuickBooks. Use the information from QuickBooks as a reference to create the file in the EFW2 format required for submission to your state.

On the other hand, QBO online offers electronic form filing within the system. You can check out this article: File your W-2s electronically.

Also, I'll share this article that can guide you in viewing your filed tax forms and paid tax payments in QuickBooks: View your previously filed tax forms and payments.
