Deductions & credits

That makes no sense to me.  I hold timber property as an investment not as rental property or a trade or business.  Currently the software will allow me to take more than $10,000 as a deduction without indicating that the amount is incorrect.  The software should limit the amount to $10,000 and automatically amortize the difference.  Why am I paying turbotax to calculate my taxes if the software won't do the calculations?  Do I now have to include a schedule C with no income and only an amortization expense or does the amortization carry over to the schedule 1 where it should be?
