After you file

I have read through all of these and it doesn't really answer the question.  I amended my 2018 return due to  now being able to  take the PMI deduction.  After I amended the return I noticed the "original amount" column for itemized deductions does not match the original amount on my 2018 return.  It is off by $3635.  I have zero idea why

I have gone through the original and the amended line by line.  I called Turbotax- they were of no help.
