New Sole Proprietor What Should I Be Filing?

Hi! So this is my first year filing since I started a small Storenvy shop.
I haven't received any forms (like a 1099) and I'm honestly quite clueless on what I should be doing for filing taxes, I'm assuming I'll be doing self employment taxes since it was my only job this past year. I used both Stripe and PayPal for the transactions.

I made a total of $2,637.45 for 2017 before expenses. Any idea what forms I should be looking at for filing? I was looking at the 1099 and who exactly would be the "payer" in this case? Do I even have to fill that? I did less than 200 transactions.

Thanks for your time.
