My 2017 TR shows $13,950 in itemized deductions without a Schedule A. I'm pretty sure I qualified only for the standard deduction. Was my TR done incorrectly?

If you filed joint your standard deduction is $12,000. Therefore if your itemized deductions are more than that, the SCH A would be included.

Did you file Joint?  For 2017 the Joint Standard Deduction was 12,700 + 1,250 for one spouse over 65.  12,700+1,250=13,950.
