Should I answer 'yes' for question asking if my home office is the primary place where I work? My inventory is stored in the home office 100% of the time. 'No' DQ's me.

According to the IRS, you should answer yes if  "You use your home office on a regular basis for storage of inventory or product samples used in your trade or business of selling products at retail or wholesale, so long as your home is the sole fixed location of such trade or business".
