I'm new to this, fresh out of high school from last year. I did independent IT work for a few months in the latter half of 2017. I got a 1099-MISC. I used turbo tax, and I'm almost ready to file, but my mother mentioned a self employment tax, and a hefty fee if you don't pay it.

I'm confused by this. That's all she said over text, and now I'm scared to death. Did Turbo Tax handle this for me? I have Turbo Tax deluxe, would I need to upgrade to self-employed? I don't want to pay that if I don't have to, I make very little income at the moment. I obviously don't own a business, I just did some simple IT work for a few months. Is this considered self-employed, and am I missing anything?

Any help is greatly appreciated. Thanks in advance!
