Thanks again, @PaulaM.Actually, the first thing I did when trying to find this information was look for the "save all documents including the worksheets" option...
Thanks@PaulaM.Unfortunately, Form 4562, Part III, Section B, column (c) "Basis for depreciation" shows only the basis of costs capitalized after rental property...
Thanks @PatriciaV!I have downloaded my return and can find Form 4562 for each property, however, Form 4562 does not show prior year depreciation or the original...
