Don't know if you can get the from the Online version. Form 4562 is just a Summary of the Depreciation for the current year and doesn't list the items.
Using the Desktop program you can get an Asset Life History worksheet but you have to do it in Forms Mode, click Forms in the upper right (upper left for Mac) You can't get detailed worksheet showing all the assets but you can get the Asset Life History on each one. It doesn't print out with your return or save in the pdf. So you have to print each Asset Life History individually.
