My return (done with Mac desktop Home & Business) was rejected because the AGI I entered for 2017 didn't match. Actually that's okay because I need to change other things anyway. The thing is, if I follow the online prompt to fix it, I fear it will just prompt me to simply fix that number and then it will just refile. Bottom line is I need to really just kill it, fix my desktop return, and then file. How can I do that?
