After you file

Why? I mail my return on 3/16/2020. I got my state return in 7 daysl I lost my husband on 5/30/2019 & had to fill feder out a form for my state return, but thought I was all set for my federal return. Please let me know if I need to send something else to federal, or if you think federal never got my paperwork & I need to re submit. I've been working on all of this since the beginning of February.

Thank you.
