Investment loss in a startup - Convertible note

[HumbleBear19]

I invested $15K in a startup few years back to fund company operations. The investment was structured as a convertible note with annual interest of 6% and payable at maturity. Company folded operations and founder is no longer responding to any communications. I hope I can claim this as investment loss this year. Please help how I can report this in Turbotax Desktop edition. 

Thanks!

Appreciate your quick response. It's a Convertible Note or loan, not equity. Should I still select Stock as investment type?

Since it is a loan, it would be deductible as a bad debt, which gets short-term capital gain treatment. It is deductible against capital gains and up to an additional $3,000 deduction per year. Unused deductions are carried over to the next year. You enter that in the Other Deductions and Credits section of TurboTax, then Nonbusiness Bad Debt. You can learn more in this IRS tax topic 453.
