Deductions & credits

as you know, IRS Form 4562 is also used to show the amortization of intangible property. for example, the amortization of refinance fees also show up on the form at the bottom. I have a form 4562 that shows amortization of refinance fees and in that row on the form, it shows an amount in the Prior Depreciation column. I then get confused understanding the difference between amortization and depreciation.  In light of this, should the amount of refinance fees that appear in the Prior Depreciation column be added to my TOTAL depreciation for the rental property?
