Like for 2019, I claimed my daughter (age 19) as a dependent in 2020. After I filed my return in Feb 2021 (it was accepted) , I discovered her refund is way higher if I don't claim her. But I tried to file her return where she isn't a dependent but it was rejected because I claimed her as a dependent on my return. So, I need to amend my return and not have her as a dependent. But I can't do that until I get my refund, then I can file my amended return. My question is should I mail in her return now or wait and e-file her return after my amended return is filed? However, my amended return won't be processed for 16 or so weeks after I am able to send it in so will her return still be rejected even if I mail it in? If I should mail in her return, when should I mail it?
