No, don't be concerned. This time of year the IRS is very busy, even though they haven't deducted the payment on the date you gave them, you are fine since you filed on time.
To verify the date that Federal funds will be withdrawn from your account, confirm that funds have been transferred, or cancel the transaction up to 48 hours before the date you designated the funds to be debited, call the IRS at 1 (888) 353-4537.
When will my tax payment go through?
