Irrevocable Trust: How to make online payment to FTB (CA)?

I have a irrevocable Trust return prepared in TurboTax Business, it said the Federal Form-1041 can be e-filed but CA Form-541 need to do the regular mail.  Money is owed to the State (CA) FTB in my case.

 

I am trying to find a way to pay online to FTB but failed to find. It seems FTB can only support Individual and/or Business (LLC, Partnership and Corp). The Trust doesn't fall into any of these two categories. I wasn't able to enter the info that the FTB payment website can accept.

 

Is anyone able to make a successful online payment to FTB (CA) for a Trust? If so, please provide some pointers.

 

Thanks,

Joseph
