Code H in box 7 of your form 1099-X means that it was a direct rollover of a Roth IRA to another Roth IRA. This rollover is not taxable. I would advise that you do not need to file an amended return. The IRS has a copy of your 1099-R but will know from the code in box 7 that it is not taxable. Just keep your 1099-R in your tax records for at least three years.
