The IRS adjusted my tax return due to an estimated payment being applied to the wrong year (2025 vs 2024). The outcome after adjustment was still a return, not a payment, just smaller than expected.
Given this situation, do I need to file an amendment correcting my return? If not, what should I retain for records of my filing for this year in case of future audit or similar (e.g., IRS account transcript, update filing in TurboTax to corred and save that but don't amend, etc.?)
