Energy Deduction
In 2018 I owned two properties. Property A was my primary home. Property B was a vacation home. In 2018 I did extensive renovations on property B. New Energy savings devices. In 2021 property B became my primary home. (Sold PropertyA.). Now the property B is now my primary home can I deduct energy savings devices that were done in 2018 when it wasn't my primary residence? I didn't deduct them in 2018,19 or 20.
