If you used the TurboTax online editions the 2020 Depreciation and Amortization report will be in the 2020 PDF download.
To access your prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/
Scroll down to the section Your tax returns & documents. Click on the Year and Click on Download/print return (PDF)
If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created. TurboTax does not store online any returns completed using the desktop editions.
The 4562 is a Depreciation and Amortization Schedule so hoping the one that says “Depreciation and Amortization Report” has details. Do I have access to that report?
Yes the Report will have those details.
