Why is my current employer not showing up?

We cannot see your screen  or return so we do not know.   Was that employer on your 2019 return?  Did you transfer your 2019 return in to 2020 at the beginning before you started to enter anything else?    If you just started working for that employer in 2020 then you have to enter the employer yourself.  Employers have until 
February 1 to issue your W-2's, so you have to wait for the W-2.

Not showing up where?  It is probably too early to import your W2 yet.  And employers have until Feb 1 to send you the W2.
