After you file
If this box in your 1040 form is checked then you are not eligible. The question is "can" you be claimed - whether you are actually claimed of not.
This is what the IRS says:

A1. You may be eligible to receive a Payment if you:
- Are a U.S. citizen, permanent resident or qualifying resident alien;
- Cannot be claimed as a dependent on someone else’s return;
- Have a Social Security number (SSN) that is valid for employment (valid SSN); and
- Exception: If either spouse is a member of the U.S. Armed Forces at any time during the taxable year, then only one spouse needs to have a valid SSN
- Have adjusted gross income below an amount based on your filing status and the number of your qualifying children.
Additional information about eligibility for the Payment can be found in the Get My Payment Frequently Asked Questions.
