Why doesn't Turbotax let me use the Energy Credit even though I filled out the Form?

[fairlambjrf]

I'm almost finished with my taxes but Turbotax says I can't get the Energy Credit because the law was not renewed yet. I went on line and found this: "For the 2018 tax year, under the federal government's Nonbusiness Energy Property Credit, the credits are good through 2019. " We put new energy efficient windows in our home and filled out the proper form in Turbotax, but the credit doesn't flow to our return.

The Nonbusiness Energy Property Credit expired after tax year 2017.  This credit was for certain high-efficiency heating and air conditioning systems, water heaters and stoves that burn biomass, energy-efficient windows and skylights, energy-efficient doors, qualifying insulation and certain roofs.

As of this date the Congress has not renewed the Nonbusiness Energy Property Credit for tax year 2018.

The Residential Energy Efficient Property Credit is in effect for 2018 to the end of 2021 - 

Qualified solar electric property, Qualified solar water heating property, Qualified small wind energy property,  Qualified geothermal heat pump property and Qualified fuel cell property costs.
