Thank you for your quick response.
As mentioned previously, we have unanticipated capital gains in 2025 and we have not paid estimated tax payments yet- as of Sept 21, 2025.
On line 24 of the 2024 Fed Form 1040- SR, I have a total tax of $2,220.
To reduce my potential tax penalty for the 2025 filing, should I make an estimated payment to the Fed IRS for $2,220?
