TurboTax, completely erroneously, associates a 1099-K with "self employment" income. I expect that 1099-K's probably are most commonly associated with self employment income, but that's not universally the case.
As to your "conflicting answers" statement, well not everything called an "answer" is correct but, too, users most commonly don't post enough information with their questions and "guesses" have to be made.
So let's start with this: If I recall PayPal used to issue a 1099-K in instances where $20K or more were processed and/or in excess of 200 transactions were processed. If that's still the case, that's a LOT of money and a LOT of transactions, which I least suggests a profit-seeking motive. So what,exactly, was the nature of the "personal property" sold? How did you acquire this personal property. Why were you selling it? Where were you selling it? Where are you entering this information in TurboTax? It seems that if you're only entering "revenue" numbers - the information off the 1099-K - there's no way you can have a "loss" and entering costs associated with this revenue isn't going to fix that. You need to explain what's going on here.
