Paying PAYG & GST to ATO

I need to pay my GST and PAYG to the ATO.
I tried raising a Payment with 3 rows (GST received, GST paid, PAYG), but it won't let me save it with a "Postings don't balance" error - I think because of the negative number.
So I raised a journal with 4 rows like the video suggested (GST received, GST paid, PAYG and bank) and all looks good.

But how do I actually pay the ATO?
Do I create a payment with one row and generate the ABA file from there? I can only use one account and it is duplicating the journal.

So maybe I can't generate an ABA file and I have to use BPay.
