How do you print your depreciation schedule to see prior deprecation taken?

Save a PDF with the worksheets in the print center.

If this is for a prior year return the PDF you can download now already has all the worksheets included.

Don't know about online or if there is a detail worksheet,   But my notes for the Desktop program says.....

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.

Scroll down the list of forms in your return to a Asset Entry or Asset Worksheet and open it.  Then down on line 14 is a QuickZoom button to Asset Life History, Click on that.

If you are trying to match your depreciation for an asset that you did not start to depreciate via TurboTax, it will be a manual process.  As @Critter-3 and @VolvoGirl mention, TurboTax will update any prior depreciation you took in previous years automatically.  In any tax return, the depreciation worksheets will (or should) be printed out with the tax return.  If you need to enter any of this information into TurboTax this year, you may need to look through your prior tax return paperwork to find it.  TurboTax may not otherwise automatically calculate the numbers.
