First time posting a partial payment towards my GST account. Not sure how.

SOLVED

So in previous years, when it came time to pay our GST remittance - we were able to pay it in full by using the "Make other payments" window by entering the "Paid on purchases" amount as a negative, and the "Charged on sales" amount as a positive. Entering it that way automatically displays amount I am supposed to pay as the payment - but what happens if I have to pay that amount in pieces? From 3 different accounts or at different times for example. Currently, my GST account balances are as follows

Charged on sales:                $16,236.39

Paid on purchases:              -$5747.03

Payment Amount is displayed as $10,489.36

How would I make an entry to reflect a payment of, say $950.00  towards what I owe?
