Applying for EIN for SMLLC Subsidiary

Greetings, I am trying to apply for EIN for my Subsidiary SMLLC (100% owned by the parent LLC). I am confused regarding Responsible Party on the Online EIN application.

Since an Entity is not longer allowed to be the Responsible Party, if enter my name and SSN as the responsible party, how will the IRS be made aware that the application is for a Passthrough Disregarded Subsidiary and not a SMLLC? I didn't see a line/space for a proper "authorized signor" signature either. I just need the EIN to open a bank account to be able to fund the subsidiary and it won't have employees either. Any suggestions will be greatly appreciated. Thanks in advance:)
