The short answer
AMZN Mktp US is listed by Amazon as a descriptor for an Amazon.com purchase. It does not, by itself, establish a third-party seller or authorization. Match the posted entry in Your Transactions; the example suffix R57TQ0XY1 has not been independently mapped to an order.

What AMZN MKTP US establishes
Amazon’s descriptor table places AMZN Mktp US alongside several Amazon.com purchase labels. The string does not establish whether an item was sold by Amazon or a marketplace seller. Find the seller and exact order in the purchase record rather than guessing from MKTP.
A bank entry can also be a payment-method authorization rather than a completed charge. Open the bank’s detail view and record pending or posted status before comparing totals. Check Your Transactions and the associated order number using the account that placed the purchase.

Amazon charged me twice for one order
Amazon explains that a split order can produce separate charges when its parts ship. A pending authorization and a posted payment are also different entries. First determine whether both entries are posted, then compare the individual shipment amounts with the order record.
Illustrative example: an order containing $18 and $12 items could be reconciled with two posted payments totaling $30 if its shipment records support that split. This arithmetic does not prove that two matching bank entries belong to that order. The Amazon reconciler can suggest amount combinations; confirm them against order details. Read the duplicate-charge guide for the pending-versus-posted distinction.

When the record still does not match
Amazon’s help page suggests checking purchases made by someone else with access to the card, additional cards and delayed shipments. Search the relevant accounts and receipts, and preserve both posted entries if you suspect a duplicate. If no record explains the payment, use Amazon’s customer-service channel and notify your issuer about any suspected unauthorized payment.
Does MKTP always mean a third-party seller?
The inspected Amazon table identifies an Amazon.com purchase and does not establish that exclusive distinction. Confirm the seller in the order.
Can a canceled order still show on my statement?
Amazon says an authorization may remain visible for an order canceled before shipment. Ask your issuer whether the entry is pending or has become a posted debit.
