Trying to Amend 2017 return due to new tax law allowing PMI insurance to be deducted. When I amend it does not change my return. Is the software not updated yet?

"I see you found my answer unhelpful", can you clarify?

This answer was in fact helpful.  I did not see the bottom portion of the response from my mobile phone that clarified the limitations.

Oh great!  Thanks!  Glad to be able to help.

But there is no place to enter PMI box 5.  WHERE?

Turbotax was updated to allow the deduction for mortgage insurance premiums as of February 22, 2018. Check your 1040 to see if your Line 40 itemized deductions amount and your taxable income on Line 43 changed. Line 40 should increase by the amount of the PMI.

I am trying to amend my return to add the PMI and it is not making any changes to my return.
