in part the correct answer depends on
1) whether you are in fact eligible to be claimed as a dependent by your parents
You could be claimed as a qualifying child if all these tests are met
- You have the same principal abode as the other party for more than ½ the tax year. Temporary absences like for school are ignored
- If not a full-time student (any part of any 5 months – in a letter ruling the IRS allowed the month the student registered even though classes didn’t start until the next month), you’re under 19 at the end of the tax year. If a full-time student under 24 at end of tax year.
- you haven't provided over ½ your own support
- you didn't file a joint return unless there was no tax liability but merely filing joint to facilitate refund of taxes withheld or estimates paid
Or as you could be a qualifying relative if all these tests are met
You’re related to the other person or, if not, lived with the other party for the entire year and
- your gross income for 2022 less than $4,400
- the other party provided over ½ your support
- you aren't a qualifying child of another taxpayer
2) say you are their dependent. if you haven't filed yet, just change it. If you have and it was accepted you'll need to file an amended return. if rejected just change it and re-e-file.
3) if you file did file and it was accepted then then they should not be able to e-file.
