Amazon vine 1099nec

Have all my income entered in TT about $90k in income and have a expected refund of $757. I'm in texas so only federal taxes. I then entered my 1099nec from the amazon prime progam totaling a little over $10k.  After doing that my expected return dropped only by like 200$ to an expected refund of $550 so im only paying around  200$ in taxes on $10k worth of items from the progam. I had kinda worked myslef up and was actully expecting to owe a significant amount in taxes (around $2500)  for participating in this amazon program.  

 

So my question is does this sound right? 

 

I feel like the math isnt mathing.

 

Also i know there is a debate wether we have to enter it as a hobby or report it as Self-employment. The thing is when i enter it as SE income it actully increases my expected refund by over 2k. That really doesnt sound right either? Am i missing somthing?
