You're not supposed to pay personal expenses with a company credit card or a company checking account.
All payments from an employer (the C corp) to an employee are supposed to be included in the wages on the employee's W-2.
It's not just a question of how to report it on your personal tax return. There's also a question of how to record it on the corporation's books and how to report it on the corporation's tax return.
I think you need a meeting with a local accountant to help you straighten out your accounting and payment practices.
