What subtraction are they requiring me to put in on Schedule A-1, Schedule A. It says misc type must be entered.

You may have a description for a miscellaneous itemized deduction in your Deductions & Credits section of TurboTax which carried over to your Schedule A.   You need to review your Deductions & Credits entries to determine whether you entered a deduction as a miscellaneous expense.  With a few exceptions, miscellaneous itemized deductions are no longer deductible.   

Another option is to delete Schedule A given that TurboTax compared your itemized deductions to your standard deduction and the numbers favor the standard deduction.  Thus, your Schedule A does not appear relevant at this point.  Here are the steps to follow to delete Schedule A .

1. Open or continue your return in TurboTax.
2. In the left menu, select Tax Tools and then Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the form/schedule/worksheet in the list and follow the instructions.
