Is there a way to expedite a return if your trying to pay?

So I realize you can apply to expedite a return if your due a refund but what if you owe and you're wanting to pay quickly? I am in the middle of trying to close on a home & they MUST have proof of all taxes paid. I see it has been received but not processed. I am very concerned I will lose this home if I can't get this paid quickly. I have gone to the local IRS office twice now, so far no luck. Anyone know of a way to expedite the process so I can pay what I owe?
