Date for an automatic withdrawal has shown on the extension approval letter.

I requested an automatic extension for my client on January 21st, 2025.  Included with the extension request form was a payment that was to be automatically withdrawn on extension approval.  The extension request was accepted by the IRS.  I printed out the approval letter by Lacerte reporting that the extension was approved.  I noticed, and this is my concern, the approval letter from Lacerte indicates that the extension payment will be withdrawn on April 15th, 2025.  I was concerned about this as in past extension requests the payment was withdrawn upon approval which was far in advance of April 15th.  I inquired to Lacerte if the withdrawal date shown on their extension approval letter was provided to Lacerte by the IRS.  The Lacerte agent made an extensive effort to arrive at an answer but was unsuccessful.  The agent suggested that I should call the IRS for the answer.  I explained that I would be most happy to that and that I will.  However, I must be made aware as to the date of withdrawal as shown on the approval letter.  I will need to know WHO PROVIDED THE DATE FOR THE PAYMENT WITHDRAWAL.  Again, I inquired to the agent but was sent various published details on tax payments; none of which was provided the answer.  My question goes out to the community if anyone else has encountered this situation.  My concern also is the tax payment was extremely large ($ 130,000) and there will be a two and one half-month charge for interest and also late payment of tax if the tax payment has to wait until April 15th to be withdrawn. Any responses will be greatly appreciated, jflangonejr@gmail.com.   Thank you, tax preparation community.
