You're involved in (at least) two different threads that are are going in all different directions.
Notice that there is no specified place, in TurboTax (TT) for a 1099-K. That's because you are supposed to know what the income is for. The above doesn't tell you that it isn't taxable. It just tells you how to enter it, in TurboTax, once YOU decide it isn't taxable.
The other thread (https://ttlc.intuit.com/community/tax-credits-deductions/discussion/re-where-do-i-write-off-obsolete...) tells you how to determine if it's taxable and is supported by other high level users and this TurboTax "fact sheet" https://turbotax.intuit.com/tax-tips/self-employment-taxes/a-tax-filing-factsheet-for-ebay-sellers/L...
It's my opinion that, based on your description, you just have an online "garage sale".
