Non business bad debt to be reported

Is this correctly treated as a nonbusiness bad debt?

This TurboTax Help states:

To be deductible: 

• The debt must be a bona fide loan with an expectation of repayment and may include interest and a promissory note.
• The debt must be 100% worthless before it can be deducted.
• Documented efforts to collect the debt must be made, such as letters, invoices, and phone calls.

Is 2025 the right year to claim the loss based on when I determined it’s uncollectible? 

A bad debt deduction must be taken in the year it becomes worthless.

On Form 8949, is it correct to report: * Proceeds = $0 * Basis = $30,000 * Description as “Nonbusiness bad debt”?

Correct, and it is reported as a short-term capital loss.

Are there any additional statements or documentation I should include with the return?

Code the transaction as a nonbusiness bad debt and TurboTax prepares the appropriate additional statement or worksheet.

In addition, IRS Publication 550, page 84, explains nonbusiness bad debts.
