Where do I report my Amazon FBA income/expenses in TurboTax?

I have received less than 20k from sales (I have only sold a few items), so I didn't receive any forms in the mail.  I am currently in the income section and I am not exactly sure where to report this.  I think it would either be:

- Self-Employment > Self-employment income and expenses
or
- Less Common Income > Miscellaneous Income, 1099-A, 1099-C

2019 was my first year selling stuff online so if anyone is knowledgeable about this stuff could you please help me out?  It would be greatly appreciated!
