I have reconciled payments in my bank statement that are not matched to specific bills, how do i fix this?

I want to ensure the payment will match the correct bill, suerichard.

I'm happy to help you fix the reconciled payments that don't match your bills in QuickBooks Online. This way, your books will always be correct.

I'd advise you to manually unreconcile the payment and match it to the bill right after. Let me show you how:

1. Go to the Accounting tab and pick Chart of Accounts. 
2. Choose the account and click View Register. 
3. Hit the transaction to expand the view. 
4. Tick the column until you see a C or Blank. The payment will go back to the For review on the Banking page.
5. Click Save.

Once done, match the payment to the correct bill in the Banking tab. Follow the steps below: 

1. Go to the Banking tab on the upper left side. 
2. Select For review tab. 
3. Find the payments and click Match. 
4. Follow the on-screen instructions.
