I have somewhat similar question but instead of checking the box to where someone can claim me as their dependent. I didn't check the box. It was an honest mistake It was my first time doing it since I didn't get qualified for the stimulus check and my mom think we can do a non filer form since I don't get paid much last year and she can still put me as her dependent. but the IRS accepted my efile. so when my mom tried to put efile her tax with me as her depended it gives her an error because of my SSN being accepted already by IRS. Can I amended that form? so my mom can file me as her dependent. we got an advised from H&R block to mail the 2019 taxes since we can't do anything electronic anymore. I know I am not eligible for stimulus now if someone is claiming me. And i felt bad that my mom can't claim me even though she can. pls we need your advised.
