Creating Vendor payment with tax deducted

Creating Vendor payment with tax deducted

Hello i would like to create a function in zoho deluge to create automtically vendor payment with tax deducted.
There is no problem creating a vendor payement without taxes for the bills. 
I dont see the input of the account of the tax and the amount 

I tried adding the amount of the tax in tax_amount_withheld  but i got this error 


I would like to use this inputs in the screen for deducted tax where i choose the account and the amount in the vendor payement api
