What to do with a printed check if the buyer changes his mind about buying?

Question

Electronic commerce

Good afternoon, please tell me what to do in this situation:
The issue is with printing a check and sending it to the Federal Tax Service, for example, in the evening the goods are given to the delivery service and a check is attached to the goods, suppose the goods were not purchased by the buyer (the courier did not get through, did not like the goods and the buyer changed his mind), as a result, the goods are returned back by the delivery service to the online store, what about the already printed check and the data on the purchase already sent to the FTS? Is it possible to somehow make sure that only confirmed purchases are sent?
Perhaps send an electronic check and generally cancel the purchase, only upon confirmation of the customer's order pickup from the delivery service?
ps naturally we are talking about the case if the courier service accepts payment from the client in cash or by card.
(or maybe in this situation the check should be generated and sent by the delivery service, since we have an agency agreement with them?).
I will be glad to any comments on the case, thanks!

Answer 1

A version of actions has appeared - as in the case of the return of goods from the buyer, the employees of the bank module voiced this option as correct, I will leave it here for now
