Good evening. I used to think it was complicated, but I was able to figure it out in detail. The blog
https://myrealprofit.com/blog/1099k-for ... n-sellers/ was a great help here, it's very detailed and easy to understand what Amazon 1099-K is and how to work with it correctly. There is nothing complicated, you just need to understand it once and you will be able to do everything quickly and correctly. In any case, you can always contact support.
