I neglected to include a 1099-INT on my 2023 tax return filing. The additional Fed & State tax I owe is $649 & $108 respectively. To meet the 4/15 deadline to avoid any penalties/interest, I paid IRS and State $700 & $120. After entering the 1099 info, I then entered in the 'Payments with Extension' section under 'Other Income Taxes' under 'Deduction & Credits', the amount of $700 in the 'Payment with 2023 federal extension' data field and the $120 in the 'Payment with 2023 state extension' data field. The State calculates correctly a refund of $12, however the Federal Tax is still showing tax due of $649. The Federal Tax I believe should show a refund of $700 - $649 = $51. Am I missing an entry somewhere?
