What happens when you get to Quick Employer Forms?
The Quick Employer Forms link has been moved for TY20. In TurboTax Online Self-Employed, click on Tax Home on the left-hand side. Scroll to the bottom and click Your Account. Click the link for Create W-2s and 1099s. This link should work for TTOnline.

Those of us who do just one or two TTax returns each year will appreciate not having to search "the community" in order to figure out (or in my case, re-discover) how to do things that ought to be intuitive and/or visible in helpful menus.
Access to QEF and the ability to eFile 1099-NEC, 1099-MISC & W2 forms really is "online only."
