Follow the steps below to change whether or not you will be claiming yourself.
1) Sign into TurboTax Online
2) Continue your return by click Taxes > Tax Timeline > Take me to my return.
3) Go to Personal Info > Personal Info Summary > and click Edit to the right of your name.
4) Scroll down to Question 3 - Someone else can claim me on their tax return.
a. If you select yes – someone can claim you
b. If you select no - you claim yourself
What if I graduatedMay 2018 so my parents can claim me and i am claiming myself but i supported myself and paid for my expenses from July-now so its pretty split between 2018..do I say YES or NO to "Did you support yourself in 2018"
If you were under the age of 19 during 2018 then you are their dependent ... I highly doubt you moved out July 1st and had absolutely no support from your parents for the last 6 months ... are you still on their health or auto insurance or cell phone plan ? And if you made less than 12K it makes no difference to your tax return anyway.
