My tax payment still hasn't been withdrawn, is this normal? My scheduled date was the 7th of this month

It is normal that the IRS  may take longer to deduct your payment for taxes owed. You can call the IRS e-file Payment Services 24/7 at 1-888-353-4537 to inquire about or cancel your payment, but please wait 7 to 10 days after your return was accepted before calling.

Yes, this is normal. Please see the article below for additional info on this.
