I know a way on how you can register the fraudulent check in QuickBooks Desktop (QBDT), @fdanielo1.
In QBDT, you can enter a journal entry to record it. First, you'll have to create an expense account for the fraud. To create one, I'd recommend consulting your account. This way, we can ensure you'll record everything correctly and prevent messing up your books.
Before making any changes in your company file, please create a backup copy first. Doing this will ensure you have the original data you can restore in case of accidental data loss or damage.
Once done, you can debit the amount for the fraud expense and credit the account that the fraud check was used for. You can also add a memo to input a description of the transaction. This process also requires assistance from your accountant. If you're not affiliated with one, please utilize our Find an Accountant tool to look for one near you.
