Deductions & credits

 I have already filed as not dependent. I need to amend it to be filed as "can be dependent". I have a W-2 and my income is $8010. I am a full time student. 

So my questions are:

1. Do I wait to do the amendment till the current one I filed is accepted?

2. Should my parents wait till my amended tax form is all accepted?

3. Or they can file using me as a dependent? Currently they have filed extension and plan to finish their returns in next few weeks.

 

Thanks,

Sandhya
