I have purchased energy efficient HVAC equipment and IRA.gov states it is worth more of a tax credit than turbo tax is saying I get. Is anyone having the same problem?

I bought a Air Source Heat pump and I should be getting a $2,000 tax credit and it won't give me that.  I also had insulation added in my attic from a contractor and it is suppose to be 30% up to $600 as well which it is not giving me back.
