Is there a way to figure depreciation that is used for our 2 small SP business & 1 rental prop using last years return? Tax preparer passed away & I have no worksheets

Sadly, my tax preparer passed away a month ago.  I am pretty familiar with tax forms and feel I can complete this using the turbotax business/self employment software. The area I am most concerned is areas of depreciation for property use for our 2 very small businesses (sole proprietor)  I am completing Sched C for both businesses and also the Sched E for our one rental property.  The sched E consistently shows a $1818 depreciation expense even going back to 2004. we have had the rental since 1997. 

The only item showing on the 4562 sched is the last year credit for an auto put in place in 2012.

Any assistance would be helpful!
