Why is Tab no longer advancing to the next line?

I appreciate you for bringing this to our attention, Finance.

I understand that using the tab key to move to the next line when entering multiple lines on a deposit in QuickBooks Online (QBO) is important. As a workaround, you can manually click the correct line.

 It appears that this issue had a previous investigation (INV-104271) that was resolved, but since it's still occurring, I suggest contacting our support team. They will securely access your account and provide possible solutions to address your concern. To contact our support team, follow these steps:

1. Go to Help.
2. Select the Search tab, then choose Contact Us.
3. Type in your issue or concern in the field.
4. Hit Continue.
5. Click the Chat or Callback option.

For reference, check this article: QuickBooks Online Support.

I've included an article that will help you categorize your transactions uploaded to QBO: Categorize online bank transactions

Please let me know if you have follow-up questions about the tab key not advancing to the next line or anything else in QuickBooks. I'll be more than willing to answer them, Finance. Take care always.
