I appreciate your time joining this discussion about splitting bank entries, @XenaXena.

Before anything else, may I know which instructions in this thread did you follow? There are several topics in this thread and I need to be sure I'm on the same page with you. Any additional details will help me provide an accurate resolution to your concern.

Also, I'd like to know which version of QuickBooks are you using. You can find it using the steps below:
 

1. Go to the Gear icon and select Account and Settings.
2. Select the Billing & Subscription tab.
3. Your subscription is shown below your company ID. See this sample screenshot:
   

If you're trying to split a bank entry, you can use the split option in the banking page. Here's how:

1. Go to the Banking menu.
2. Click the bank transaction you want to split.
3. Press the Split option.
   
4. Make sure to fill the Amount column.
   

If you can't find the Amount field, try opening your account in a private window. This will not save any history, so it's a great place to identify issues in the browser. Use these keyboard shortcuts to launch a new private window:

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

You may try a different browser too, and see if the problem persists there. If you can use the feature in QuickBooks without any issues using the workarounds, clear the cache to start with a clean slate. 

Please add the additional details and result below. I want to make sure this bank entry is resolved for you.
