If four equal ES voucher payments add up to 110% then you met the Required Annual Payment.
Applying some refund to 2025 tax merely reduces the amount due on Tax Day
But, you can't make four equal ES voucher payments now because we're coming up on the third payment.
The amount applied will go toward your first voucher payment and the second if it is two times the voucher payment. In which case two payments are needed.
This eliminates any penalty.
