If you have been reporting it under the Inventory section, you don't receive the deduction for the purchase until it is removed from your business.
That means that if you sell it for the same price as what you paid for it, the income and deduction will be the same, resulting in a $0 profit, and therefore $0 tax.
If you have unsold inventory that you convert to personal use, you need to tell the to the program. The program won't give you the deduction for the Inventory, but no tax would be due. So it would essentially mean that you bought the items yourself, with no tax deduction or other tax consequences.
