Hello there, @dirtdiva79. 

Once you apply payments to the invoices, it clears out the invoices in the Account Receivable (AR). You can use this article to review the details about recording invoice payments in QuickBooks Online: Record invoice payments in QuickBooks Online.

You can also create a journal entry to clear the overdue invoices in the AR without removing the time and material. In this process, I'd recommend consulting your accountant for further assistance. This ensures you'll be using the correct account and properly set up. This keeps your data accurate.

Here's how:

1. Go to the +New icon.
2. Select Journal entry.
3. On the first line, select an account from the Account field. Depending on if you need to debit or credit the account, enter the amount in the correct column.
4. On the next line, select the other account you're moving money to or from. 
5. Enter all the information you need.
6. Then, click Save and Close.

If you're looking for an accountant, you can open our ProAdvisor Page. From there, you can follow these steps:

1. Pick an option of what expertise you need to find.
2. Enter your city or zip code, then hit Search.
