After you file

IF I understand the info correctly, about 2/17 the Amend form will be available on Turbotax...BUT you are indicating I must wait for IRS processes refund before i do? I thought the sooner I amend sooner that IRS can correctly process for refund. Also, as this impacts the State filing, does Turbotax system allow e-file amendment as well? I paid for th e-filing of my State return (the Turbotax PC version I bought at Costco including the Federal filing and access to a state return).
