Parent trying to make amendment to claim me as dependent
So I finished filing my taxes a couple weeks ago and my mom just called to say she needs my 1040 to make an amendment because I filed as Single rather than say I can be claimed as a dependent. She said it would make a large tax difference for her. I explained that I don't believe I can be claimed as a dependent but she said she with a tax lady who disagrees and says I am incorrect.
In 2019 I turned 24 in January, I was a full time student until May and I made more than the $4,000 minimum for claiming a relative.
What should I do?
