I filed on February 8

What am I supposed to do when the IRS keeps telling me it has not processed my return, and I will be charged penalties and such?  I also haven't gotten my first stimulus check.  Could that be why?  When I look at my IRS account where I owe back taxes, it shows 0 in the first stimulus check amount and $600 in the second stimulus check.  I did get the second stimulus check.  I'm not sure if the 0 means I'm not going to get it at all or if I just haven't gotten it yet.  I also got the third stimulus check.  I also did what I was supposed to when filing the 2020 tax return to try and get my first and second stimulus check.  How are we supposed to find out why we're not getting a first one.  Nobody ever brings up how to go about finding out how to find out why you haven't gotten the first one.  They're all about the third one now.  Now I have to worry about if I'm supposed to do an amended return since the IRS hasn't processed my return.
