Good day, usernoraliz.
Stripe brings the transactions to QuickBooks Online and will be posted into the account based on the mapping. I suggest you review the integration set up to correct any issue that causes this behavior.
Also, you'll want to reach out to Stripe's support or to the third-party you use to link the two platforms. They can further investigate and assist you with it.
I've added these links if you'd like to process payments within QuickBooks Online.
Keep on posting here if you have more questions. I'll be here!
