Yes it is functioning now for me too. I was able to get the $600 max for the high efficiency furnace. However I had to search a bit and ultimately drill into the deduction selection that is titled for "Boilers" to find that behind that selection, they further describe that it is for Boilers and Furnaces. TT should probably better title that deduction selection to feature furnaces. That would probably be the majority of tax payers purchases vs. boilers. Hope everyone is set now. Looking forward to the update for entry of K-1's to continue to complete the return. Supposedly next week
