Yes, undoing thousands of transactions will be a lot of work. The fastest way to offset the amounts would be to create a journal entry. However, I'd recommend consulting your accountant before creating the entry. They can guide you with this or even provide you another option to offset the amounts.

We appreciate you for considering LieraMarie_A's suggestion in correcting your future transactions.
