I bought a rental property abroad in Dec 2021, the property was still under construction. I had expenses in 2021 (notary fees). Can I deduct those expenses in 2021/2?

The property was delivered in April 2022 and it was rented in September 2022. I did not add the property in my 2021 tax return, I am wondering if I should file an amended tax return for 2021, or if I could still add those 2021 expenses to my 2022 tax return.
