After you file

Thank you for responding. I'm sorry for my ignorance on this topic. I'm still confused, so all of the criteria is true except my line 16 is zero. Did I make a mistake? I had income in 2020, then lost my job and began receiving unemployment. I had 10% withholding.  So am I now not getting the refund?

Is there a chance I could get anything back regarding the other credits I had? I really appreciate your time. Thanks for helping those of us who are lost this year. 

I would be so grateful for any more clarification on why that line 16 is keeping me from the exclusion.
