I dont see a form 4652 ammoritization of rental ,where can it be found

Form 4652 is used to report depreciation and amortization for certain types of assets. If you have only residential real estate, improvements, etc., and added no assets this year, your return may not include Form 4652.

However, TurboTax creates a worksheet called "Form 4562 Depreciation and Amortization Report" that is always included with your tax return if you have any depreciated assets. See screenshot below - click to enlarge.
