I received a corrected 1099-INT for 2025. I have already submitted my 1040 via TurboTax with the tax due to be paid via ACH on 4/1/26. I saved my return under a new name, removed the old 1099-INT and downloaded the corrected one from my brokerage. It resulted in $30 less of taxes. I have to pay quite a bit in taxes this year and this refund is inconsequential to me. Is there a way modify my submitted filling if it has already been accepted but the taxes have not yet been withdrawn from my account? I'm inclined to just let this slide unless it will cause some other unforeseen complication. One other point to consider is I realized this year I did not calculate cost-basis for ISOs I executed in 2024 correctly, so I have filed a 1040-X for 2024 which will result in a large refund because I essentially paid double-tax. I'm concerned if I file amended returns back to back it will flag me somehow. This was the first time I have ever had to amend a return.
