Hi anyone having the same problem I did! The only thread I found regarding this was too old to allow replies.
The Etsy email that went out sends you to a TurboTax error page.
Instead, from your Etsy Dashboard go to the Finances Tab: TurboTax for Etsy (last option)
Hope this saves someone a lot of grief. Good luck!
I did it exactly like that, from the finances tab. Didn't work. It even showed an Etsy logo at the bottom the entire time. I thought for sure it was going to work. No 50% off when I paid at the end. Pretty disappointing.
TurboTax discounts were not honored on non Etsy sites as well. Have a few ticked off friends that ended up going elsewhere.
