I called customer service as well and they gave me the run around. I explained to them that I have been using this feature for at least a decade as well, and my refund is always over tax fee amount. I also mentioned that other people were experiencing the same issue and they said "we haven't heard any complaints".
These were their (ridiculous) recommendations: Clear the browser history, clear the cache, check to see if your computer/phone/app requires any updates. I did all of those things and it's still not working. Next I will try using Google Chrome instead of Safari.
If that doesn't work I'll be going to H&R Block. I hope the technical issue is solved soon for everyone.
