I logged into my Etsy Shop Dashboard today and saw a notification in the Finances tab. There, I discovered a new link called "TurboTax for Etsy" (second image). This took me directly to a landing page (first image) for starting either TurboTax Self-Employed for $45 federal (+$40 state) or TurboTaxLive Self-Employed for $85 federal (+$50 state).
These are the in-browser online versions of TurboTax Home & Business (H&B is the CD/downloadable software standalone version). From what I understand, that is the only difference. Otherwise, Self-Employed and H&B perform all the same functions.
I tried to get a link to it, but the URL seems Etsy-user unique (I couldn't open mine in Incognito), and I could not find any advertising for this outside of my Etsy dashboard and the user-specific link. I also never received an email about it from Etsy. I have no idea if this is targeted to some Etsy sellers or available to all, so YMMV. Apologies for not being able to offer more than screenshots.
