Hobby income or how to fill out Schedule C?

[lenben-62]

I sold 10 items last year on eBay for roughly $600.  I understand with hobby income I would need to put that entire amount and could not deduct any of it.  However, with Schedule C, I could enter the cost of shipping, eBay fees, PayPal fees, and packing tape.  The amount I ended up earning was closer to $125 in the end.  What I am unclear on is where on Schedule C I would list these various things:

- Shipping/packing tape - I believe per the Schedule C instructions, this would go on line 18?

- eBay fees - Would this amount be listed in Part V - Other Expenses?

- PayPal fees - Would this amount be listed in Part V - Other Expenses?

- Original cost of the items - ???

(Keeping in mind that some of the items I purchased were purchased 10-15 years ago; these were personal items I decided I no longer wanted.  I'm not buying items with the intent on selling them at a profit; I'm simply trying to get rid of items I no longer want around the house, and if they make me some $, great.)   

The "Cost of Goods Sold" section I would have no clue how to fill out; it doesn't really apply as I don't have inventory piled up around the home, since again these are items I simply no longer want or need.

I had seen TurboTax's 2020 article that indicated if I paid more for the original item than what I made back on eBay that the IRS wouldn't care about that cost and consider it an "online garage sale."  However, that PDF/information is no longer available on the IRS site, so I don't know if they have changed their policy on it?  It seems like they have changed their focus to "gig work" where they talk about online sales, but that article is as clear as mud to me.

I want to do what is right and fair, and while I'd like to continue selling items on eBay, it seems like such a hassle when it comes to figuring out what to do come tax time.  If I only had more confidence in what I should put on Schedule C, I think I would feel better about it.  Hope someone can please help.  Thanks!
