I'm trying to figure out how to pay my deferred social security tax on the IRS website. I don't see any way to apply it to the deferred payment owed. So, how do I do it?

I'm self-employed and currently owe the first half of my deferred social security tax. But I can't figure out how to pay it on the IRS website so that it will be applied to the deferred payment and not my regular installment schedule.
