Taxpayer was the sole shareholder and officer of a corporation. In order for the company to get an American Express card, the T/P had to guarantee payment of any debt incurred on this account.  When the company went out of business, with no assets, the T/P agreed to pay the balance owed to American Express over a period time and I have deducted those payments each year as a non-business bad debt short-term capital loss.  The ProSeries form seems to preclude situations that did not result from the T/P lending funds that were not repaid.
