Incorrectly filed returns with the TSP as an IRA in past returns
I have the Federal Employee TSP plan. For the past 2 years I have filed returns where I have entered my TSP contributions in the IRA contributions section in TurboTax. I was completely unaware that the TSP contributions were actually entered on our W-2s. Therefore, is this something that I need to correct on past returns, or since the returns were already accepted just leave them alone?
