Check the instruction cover sheet and see how you were suppose to pay it. Like by check, etc. Did it print out a 1040 V voucher slip? Look at your return and see if the bank info is printed on it at the bottom or just xxxx's. When did you mail it? Maybe the IRS hasn't processed it yet. If they had they would have sent you a bill for the tax due. Did you mail federal and state in separate envelopes to different places? If you mailed them together then one wasn't processed at all.
