I have already received back notification (from both Fed & State) that my submitted returns were accepted. Unfortunately, my check (for owed-taxes) was sent along with the extension-application-voucher (to that address, payable to US Treasury) instead of with the submitted-payment-voucher (to a different address, payable to IRS). Should I put stop-payment on the 'extension-check' and submit another submitted-payment-check?
