It is a little bit confusion by IRS "Call IRS e-file Payment Services 24/7 at [phone number removed] to inquire about or cancel your payment, but please wait 7 to 10 days after your return was accepted before calling."
I think it is reasonable to count 10 day from "the specific date" if the tax payer specify the later day, such as April 9. I am in the same boat. My tax got accepted in March, and I specified the April. The CA state withdrew the money at the exact day, but IRS has not yet.
