I'm trying to enter multiple homes under "how many homes had qualified energy property installed" and even though I enter both with complete addresses I get a red pop up?

Two possibilities:

1. Some items are restricted to principal residence while others include a second home, just not rentals. Qualified energy efficient improvements are limited to your principal residence. Residential energy does allow a second home.

Please double check the credit you are taking and the homes allowed. About Form 5695, Residential Energy Credits
