FYI .... the IRS itself does a complete efile shut down for all returns from early December until mid January every year to make the switch to the tax year. So if you don't get it filed before that time frame you will have to wait until the efile system is open again. You have 3 years to amend AND it takes 4 months or more to process an amended return that is paper filed AND you should not file an amended return until the original return has fully processed .... so each taxpayer will need to decide on the best plan for their circumstance.
Of course since efiling an amended return is new for everyone it is unknown if TT will have that option available when using the downloaded version and no instructions have been posted as of yet ... so this is a wait and see.
