HOW DO I CATEGORIZE MY CHECKING ACCOUNT EXPENSES?

Just create a expense account and classify on the basis of type of expense it belongs to like as given below 

Hi meridianconnecti!

Let me show you how to categorize your downloaded bank transactions.

If there's a matching entry in QuickBooks Online, you can match them. This will prevent it from duplicating. If QuickBooks Online found a matching entry, you'll see the green Match. Just review and confirm it.

1. From the Banking page, select the transaction and click Find match.
2. On the Match transactions page, find the matching entry. You can filter the dates and transaction type.
3. Tick the box and tap Save.

You can also manually select a Category if you want to add it as a new transaction. When everything looks good, select Add. For the detailed steps, here's how to categorize and match online bank transactions in QuickBooks Online.

In addition, if you're unsure what category to select, you'll want to seek some help from your accountant.
