Where to enter cost of goods to offset consignment store 1099-Misc Lines 3 'Other Income'

So, cleaned out my closet, and got a 1099-Misc, but can't figure out where in TT to offset the income as reported in the 1099-Misc with my original purchase cost.

 

Does anyone know exactly the path to find this?  This is my first time with this, so I'm a little confused.

 

Thank you!
