Retirement tax questions

This does not appear to be an error in TurboTax.  Although the NY Long Term Care Premiums deduction is 20%, there is a $1,500 limit and this is a non-refundable credit.  Also, if your income is greater than $250,000, you are not eligible for the credit. Since this is a non-refundable credit, if you did not have any NY tax liability, you would not see a benefit from this credit for the current tax year.
