What box do I put expenses not covered by my employer

[SweetieJean]

That would be an employee business expense. Employee business expenses are a limited deduction. You can claim them only if:

• You can itemize deductions, and
• they exceed 2% of your adjusted gross income.

If your miscellaneous itemized deductions clearly don't exceed 2% of your adjusted gross income there is no need to go through the time consuming effort to enter them. If they are over 2%, under the deductions and credits tab at the bottom of the list under other deductions and credits. Look for other deductions.

Turbotax explains the 2% rule at this site.
