Deductions & credits

My AGI / MAGI are too high for my IRA contribution to be deductible.  But TurboTax calculates it as a deduction.  (e.g. If I put in "0" for contribution, my tax due increases; if I put in "6,000" for contribution, my tax due decreases).

 

also, there is no prompt asking if THIS YEAR's deuction is deductible.  But that makes sense because TurboTax should be calculating it on its own.

 

What's going on?
