Prepared w-2's for employees. How do I send w-3's to social security electronically?

Depends on which option you choose ... if you used the QEF tool then just click on the orange EFILE button and they are sent electronically. 

If you used the tool inside the H&B Program then you need to print off everything and mail them in... read the screen instructions.

Thanks  Hate to be so dumb, but I cannot find a QEF tool or orange submit button.  I know I submitted info electronically last year but just don't remember how.

See this TurboTax support FAQ for creating W-2's and Form 1099's - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-forms/create-w-2-1099-forms-employee...

Which did you pick on this screen?  On Windows H&B you get a choice of how to prepare them.  Mac H&B only gives you the Quick Employer Forms

Thanks  Found it
