This. The IRS will only come after you if they think you were deliberately lying. Mistakes are simply to be fixed even when they are doozies. (One year I ended up amending my previous year's return because I had managed to fat-finger an extra digit into a number. It didn't change my tax bill *that year* by a single penny so nothing looked off. It was only when I saw the huge amount of losses being carried forward that I realized something was off. I didn't get any sort of complaint from the IRS about that despite it being a 5-figure error.)
