I would like to make a payment through the IRS credit card processing system (https://www.irs.gov/payments/pay-your-taxes-by-debit-or-credit-card), as their rate is much lower than paying by CC through TurboTax.
How do I record that payment so that it is credited against my taxes due and reflected in the program? I want to have the remaining amount, net of this payment, show as the balance due on my 1040 and be taken from my checking account as I always have
The only function I see to record estimated taxes goes directly to asking for a series of quarterly payments amounts with the default 1040ES dates (1/14/25 for Q4). I don't need it to be a timely 1040ES payment, so I won't make the payment for a while. Can I still just enter it as a Fourth Quarter payment and put the date as whatever the correct Feb/March/April date is when I make it? And assume the IRS will be able to match up the SSN and tax year?
