Change in DBP Funding Method - IRS User Fee?

Does anyone know what the IRS user fee is for requesting a change in funding method that does not get automatic approval? It is classified as a letter ruling request but the fee schedule does not specifically show changes in funding methods and actuarial assumptions. I see changes in accounting method at $11,500 and then all other requests at $38,000 - big difference. The IRS does not make this easy!

$12,500. It's a letter ruling request under the jurisdiction of Employee Plans - see rev. proc. 2023-04 sec. 24.01 and the fee schedule in appendix A of the same procedure.

Thanks, I was in there but not looking in the right place. Must appreciated.
