When you filed, did you e-file and choose to have the money that you owe taken out of your bank account? If so, then you have already filed and paid. Don't send a paper copy of your return in, and keep the voucher for your records.
If you haven't e-filed and are mailing your return in, then you haven't had a withdrawal of money from your account, because how would they know without your return, right? Include your voucher with your return when you mail it in.
If I haven't addressed your concern, post back to THIS thread.
