amend her return due to her being able to claim herself instead of being a dependent on her parents.
Out of curiosity, what triggered her to get a refund? Was she claiming college credits?
I hope you verified that her parents were not eligible to claim her. There have been many young people trying to wrongly indicate their parents' can't claim them in order to fraudulently claim the $1200 Stimulus Check.
In direct answer to your question, Intuit has stupidly imposed a restriction on ProSeries that only allows you to e-file a return you have previously e-filed yourself.
