Why are my credit card debit (expense) transactions downloaded from my bank appearing the the bank register as credits?

Allow me to provide you with a few information and guide the correct entry for your transactions, cthompson4.

Generally, these credit card transactions are debts. The balance you owe increases once you enter the expenses charges you used for the card. The balance goes down by the payments you make. Since these are downloaded transactions, please know QuickBooks depends on what your bank shares with us and how they are posted online. You'll want to exclude those transactions if you're sure that it was posted on the wrong entry. To do this, follow the steps below:

2. Select the correct bank account.
3. Choose the For Review tab.
4. Put a checkmark on the box(es) of the transactions you want to exclude.
5. Click the Batch actions drop-down arrow and select Exclude Selected.
