Deductions & credits

I am trhing to finish my taxes and cannot carryover the special depreciation using forms 4562 and forms 8582 as I have $18,191 that is not carrying over into these forms that adjust my submission as done in years past.   Form 8582 detremines your maximum deduction and how do I get numbers entered into this form.  This has NOTHING to do with Section 179 as I puchased NO vehicle to write off as bonus depreation for one year.
