Form 3115 Change in Accounting method

Hello,  thanks for your help in advance.  I need to change the accounting method for 4 properties acquired in 2019 in order to be able to deduct the separate items in a cost segregation study that I had done for those 4 properties.

 

My question is:  Will I be able to deduct the items in the cost segregation study (site improvements (15 year), and Equipment/Furnishings (5 year)) in their ENTIRETY (i.g. as a Special Depreciation Allowance) for my 2021 taxes?

 

if so, Does turbotax desktop premium allow this do be done in the application?

 

thanks again
