I have a tax return that we are attempting to e file an amendment for. The amendment is for a change of dependent that was claimed on another tax return in error. According to this notice from the IRS, they said that they would allow e-filing of an amended return even if a dependent was claimed on another tax return. We attempted to e file this return yesterday and this is the response on the rejection letter.

Error Detail:
'DependentSSN' in 'DependentDetail' on the return was used as a Dependent SSN on a
previously filed tax return for the same tax period.

Error Resolution:
This reject frequently occurs when the dependent's SSN on this tax return was present as
a dependent on another tax return, or the dependent already filed a return without
indicating they would be claimed as a dependent on another return.

Anyone have any insight on this new notice from the IRS and does it work with e-filing through ProSeries?
