Deductions & credits

It looks to me that there are errors in lines 24 and 26, but hard to know where exactly the problem is without auditing the entire schedule/process of determining using prior year carryforwards.  What I do know is that I don't think I should able to use ANY prior years apprec. sec. carry forwards, and my current apprec.security deductions should be limited.  

The current year amounts seem correct; the error I think is that the system is allowing use of a prior year carryforward when it shouldn't.  It is exactly the same amount as the partial current year appreciated security deduction.

If you look at my return, I think the combination of cash and appreciated sec deductions should be limited to 50% of AGI plus any cash deductions elected for 100% deduction.  The return currently exceeds this amount by the amount of the use of the calculated allowable prior year carryforward for appreciated securities.

So, I know what item I think is incorrect but not where in Turbotax it is being calculated.  Someone who really understands the "Charitable Deduction Limits Worksheet for Carryover Contributions" should be able to identify this.
