I checked the “someone can claim me as a dependent” box on my taxes but no one claimed me as a dependent, can I still get my stimulus check?

I did the nonfile thing on the 14th of April and I saw the box saying if someone can claim me so I didn't check it and I submitted it and mins later i got a email saying

Here is your error(s): Issue      : Business Rule IND-516-01 - If Form 1040, 'PrimaryClaimAsDependentInd' is not checked, then the Primary SSN must not be the same as a Dependent SSN on another return.

The following information may help you determine the form at issue: Field/Xpath: /efile:Return/efile:ReturnHeader/efile:Filer[1]/efile:PrimarySSN

So I login in to see and I check the box and submitted it and they accepted my information same information and same ssn

I haven't got an update still and no date and my parents claimed me on their taxes but never get nothing from me and im on ssi and im full-time student I just want to know if im eligible or not because some people said i am and im not and I called the irs number yesterdaythey said they have my information on file and i told them I'm on ssi and they said i might be eligible and I told them to check if im eligible on their system and they couldn't tell me and they also said my stimulus check hasn't been issued yet and can someone tell me what does my situation mean and what does she mean by hasn't been issued yet?
