Deleting deductions in an amended return

Hello,

 

I filed my taxes on time, but realized I need to remove a deduction for health care premiums and change the amount I deducted for business related moving expenses. I had to pay at filing time and these changes will require me to pay more. 

Two questions:

 

1) Will these changes trigger an audit? I will be removing a deduction of about $9,200 for health premiums and removing around $2500 for business related moving truck expenses.

 

2) If I amend I will need to give a reason for each change. What can be said for these changes that won’t trigger an audit? 


Does TurboTax automatically calculate the additional amount due plus the penalties for paying more?
