The following diagnostic is generating:

Residential energy credits were not allowed because the improvements or property costs were not made to the taxpayer's main home located in the U.S.

Solution:

To qualify for residential energy credits (e.g., Form 5695), the improvements (such as solar panels, windows, insulation, etc.) must be made to your primary residence located within the U.S. If the property is outside the U.S., no credit is allowed.

Verify that the energy-efficient improvements were made to the taxpayer’s main home.

Confirm that the main home is physically located in the U.S.

Check if credit allowed on Form 5695 then in Screen 38.2 Child Tax Credit, EIC, Other Credits > Residential Energy Efficient Property Credit > Property > Check for overrides for the address.
