Invoice paid with prepayment and with AWT Calculation Point on Payment

Example:
I have an invoice with a total amount of 16,575.12.
Of this total amount, I have a prepayment of 15,555.75.
So
Total Amount - Prepayment = 1,019.37 (amount to be paid)

The amount of 1,019.37 is the AWT amount.
Where the tax:

IR 1.5% = 248.63 Calculation point in 'Invoice'
CSRF 4.65% = 770.74 Calculation point in 'Payment'

But I'm having trouble generating the invoice payment so that it generates the tax authority line for the AWT CSRF 4.65% = 770.74 Calculation point in 'Payment', this is because if we check the calculation there is a rounding problem, has anyone experienced this problem? And how did you solve it?

total invoice amount	16575,1200
total prepayment amount
