For the "Online" software.....Sometimes...if you get a new PDF from your Online account for that prior year, that PDF will now contain all the worksheets, including the Charitable donations listings.
IF you remember to get the Full PDF with all the worksheets BEFORE you e-file every year, then you will have that extended PDF to refer to in future years.
