I'm trying to find out how to access my 1099. I can confirm that I'm logged in under the page admin, and according to an export of my payouts I've made more than $20k this year.
It looks like I did have payments exceeding the $20k mark, but only had 186 Shopify Payment transactions. So it makes sense that I don't have a 1099 form available.
Yep the threshold to receive a 1099-K is generally $20,000 and 200 transactions. Some states such as IL, MA, MD, MO, VT and VA have lower thresholds so sellers in those states might still get a 1099-K if they're under the $20,000/200 mark.
