Where Is 2017 TurboTax Getting "Extra" Medical Expenses

[156church]

I am re-doing my 2017 TurboTax forms. 

In the Deduction & Credits - Medical Expenses section the TurboTax total is $10K. I've only entered $700 in the worksheet for Medical Professional Fees, Lab & X-ray Fees, Eyecare, Medical Travel & prescriptions. NOTE: Not my actual expenses.

Where is TT getting the extra $9,300?

A couple of common places to check (switch to the FORMS mode to see the detail worksheets) ... one is the Medicare premiums you entered on the 1099-SSA entry screen and the other is the Self Employed Health Insurance adjustment in coordination with the Premium tax credit repayment form 8962.
