I'm having the exact same issue with a Rheem heat pump water heater, QMID K3A8. When I work through form 5695 manually I see that I am eligible for the full 30% credit, but Turbotax calculates a credit of $0 with the message, "Based on what you've entered so far, we can't get you the home energy credit for 2025 and you have no credit to carry forward to 2026." My tax liability is significantly more than the non-refundable credit amount.
