Primary residence converted to a rental property

[DJC69]

Our home of 20 years was converted to a rental property in August 2022.  How do I add previous capital improvements dating back to 2004-2008, etc. to the basis?  I can combine expenses into bathroom remodel, kitchen remodel, flooring, etc.  Do I backdate?  I assume the amortization would begin the date the rental was placed into service vs. the date the work was done. Is this correct?  Thanks!

when you get to the asset entry section for the rental, you'll be asked for both the date acquired/purchased and date placed into service (first use in business). depreciation starts with the date placed into service

No.

You add up your initial cost basis (purchase price) and the cost of your improvements in order to get your basis for depreciation (i.e., it is one number).

The cost basis is the lesser of the FMV at the date of conversion  OR  the total cost basis ( original purchase price + cost to buy + improvements made up to the date of conversion).
