Recently got a letter from the IRS stating that I owed them more money and plus put up a penalty and interest on what I owed. I can see clearly that while I missed reporting a large ticket sale of stocks however, they missed the cost basis on that stock. This is the second time that the IRS is sending me a letter for a similar issue but I was able to rectify the first one pretty easily(similar to this one). Last time I just told them they had missed the cost basis but this time they did miss the cost basis but I still owe them a small amount of tax. Can I just amend my 2022 tax return and fix the issue?
