You can export a list of all payment transactions for a specified year from your Dashboard using the Available On filter. The Amount column for these list of transactions will provide a complete summary of all transactions that contributed towards the totals used to determine your eligibility in receiving a 1099-K form. If you did not qualify for a 1099-k, you can use this report to see why.
1099-Ks from Stripe to Connect Custom and Express platforms will also include all transactions processed through their connected accounts. See 1099-K Platforms for more information.
