Hurricane Irma Deduction Questions

Facts

-I took a minimal deduction for Hurricane Irma losses to my residence and its roof on my 2017 return based on damages reported to me and repairs made at that time. 

-A roof inspection in 2019 revealed substantially more damage which will require a complete roof replacement and repairs to interior walls. These repairs have not been made. 

-I submitted a claim to the insurance company in 2019 which it denied in late 2019.

-No reimbursement was received for these losses despite the fact that all of my neighbors' insurance companies paid their losses including complete roof replacements. 

-There is a link on TurboTax 2019 which provides a FEMA code for Hurricane Irma in my county and state.

 

Question: Can I deduct the additional losses first discovered in 2019 on my 2019 return, or do I need to amend a prior year's return?

 

Please note: If I have a choice, I would prefer to deduct these losses on my 2019 return. 

 

Thanks in advance for any assistance you can provide.
