Short answer Schedule C, Line 17 Legal and professional services

Legal fees to sue a customer belongs on Line 17, legal and professional services.

Why line 17

Legal fees to collect a business receivable or enforce a business contract arise out of the business itself, so they are ordinary legal expenses on line 17. What matters is the origin of the claim, not the outcome: the same fees are deductible if the case settles for nothing. If the suit is really about acquiring or protecting title to an asset, the fees are capitalized instead.
