Do I need to file an extension for 2019 if I earned less than $400 but do not have my W-2?

I do not have my W-2 for 2019.
I earned less than $400 in 2019, for one employer - the one I am missing the W-2 from.  I can't fill out my tax return without my W-2 (I cannot estimate, either).  But since I will not owe any taxes. do I need to file an extension, so that I can file after I do get a copy of my W-2?

No, you do not need to file an extension if you do not owe. Read more about it here.
