After you file

I Efiled through the turbo tax app and it was accepted. Ive never heard anything since. I filed on April 4th 2020. Everytime i check the IRS wheres my refund it tells me they dont have any information for me or I put in the wrong information. I was oy supposed to get back $13 since my mom had passed away i didnt work much I just took care of her. So im sure i was supposed to Get the stimulus as well.
