The IRS can look at your 2018 or 2019 return to issue a stimulus check.  If they do not have a 2018 return then you may be waiting for them to finish processing 2019 before they will be able to use it to issue your stimulus check.

If you used the non-filer site, you will not be able to e-file a 2019 return after using the non-filer site.

TurboTax has no control over your stimulus check, nor can TT track it for you or tell you when the IRS will issue it. Refer to the sites linked below:

You can call the IRS hotline at 1-800-919-9835 to get updates on your stimulus payment.

"Also i dont know why i am not eligible for tax return"

Do you mean you do not understand why you are not getting a tax refund?   We cannot see your return so we do not know why you are not getting a refund.  Provide some details about your situation--without any personal information.  What kind of income did you enter?  Was tax withheld from it?  

What is your filing status?  Did you double check all of the amounts of income you entered?
