If there were no other heat pumps installed in your residence, there is nothing to enter.

How many homes did you install this on?  The credit is only available to be used on your main home.

The maximum credit amount is $2,000 even if you installed multiple units.  So if you paid $10,000 for the first heat pump water heater that was installed on YOUR MAIN HOME, you would only need to enter that one.  You cannot enter anything that was not installed on your home.

The 30% credit for a heat pump water heater is not limited to your main home.

From IRS Fact Sheet FS-2025-01:

A taxpayer claiming the credit for electric or natural gas heat pump water heaters; electric or natural gas heat pumps; central air conditioners; natural gas, propane, or oil water heaters; natural gas, propane, or oil furnaces or hot water boilers; biomass stoves or boilers; oil furnaces or hot water boilers; and improvements to, or replacements of, panelboards, sub-panelboards, branch circuits, or feeders must have installed such property in a home located in the United States and used as a residence by the taxpayer. In this case, the taxpayer may rent the home in which such property is installed, and such property may be installed in the taxpayer’s second home.

This is different from other categories of energy improvements, such as insulation, doors, and windows that are limited to your main home.
