Deductions & credits

But is it working? I just tried to enter mine and it doesn't give me any change in my taxes? I had a carryforward from 2018 to 2019, after buying an EV and installing solar panels, even before the EV station was entered, but now when I enter the charging station, it tells me I'm losing all of the credit. I went back and deleted my solar, to see if maybe it was the order of the entry that affected it, but same result, when I then have the charging station entered it at first gives me credit for that but then decreased the solar panels credit, so overall, with this added expense of the charging station, I end up with the same carryfoward?
