Hi Iatros55!

It's normal that QuickBooks creates debits and credits when entering bank deposits. This happens to all transactions.

Try opening a different transaction, click More and choose Transaction Journal, you'll see the movement of funds from one account to another through debits and credits. QuickBooks uses double-entry accounting when you create a transaction, meaning it affects at least two accounts in your ledger. 

You can check the article that explains how accounts are affected by debits and credits for additional reference. You can also seek advice from an accountant.

We're always here if you need further assistance.

Have a good day!
