只能将错就错，不要报了。

第一，5% every month being late，最多不超过25%的罚款。你这个早就到了。

第二，Unfortunately, the tax code provides very few ways to avoid this penalty if the form is late or to remove it once it is assessed. One avenue you can use to seek relief from this stiff penalty is abatement, which is done after the IRS has already assessed the penalty.

那么只好这样了，等到被发现再找律师求饶吧，现在也没有办法纠正。
