Trying to figure out how to e-file my first amended return via ProSeries. I prepared the 1040X and am redy to e-file the return with the IRS only. I don't see a checkbox on the Info Worksheet that would be checked in order to e-file the amended return. This client already filed their own 2019 tax return a few months ago, so I am just filing the amended return.

Am I missing a checkbox on the Info Worksheet - I just don't see it.

Thanks for any assistance.
