Oh wait, I think I remember what part you're referring to, every year its like that, it doesn't auto fill the address...I don't think you'll see that change. 

I agree with you, why wouldn't it automatically grab the address on the tax return then let you change it if that's just a mailing address, I'm guessing because people are lazy and may not take the time to verify that the address that autofill's is the correct physical address of where the solar was installed.   

Thankfully, the % of clients that install solar each year is relatively low, and the credit is a nice hefty chunk, so you don't have to be shy about charging extra for your time to complete the form, so were not having to waste too many extra keystrokes for free!
