1) do not do anything else until the original tax return has been processed.
2) do no do anything else until the amendment is processed (that will take 9=12 months from the time you submitted)
3) once the dust has settled, if necessary, send in another amendment to correct anything left. But you really need to wait until 1) and 2) are resolved in case the IRS makes adjustments you weren't expecting.
4) be patient!
