Can I file my 2019 taxes if I have received my W2’s forms now ?

No you have to wait for the year to end.  How did you get your W2 already?  And the online versions won't open until sometime in December.  And the IRS won't start taking returns until late January.

And don't file early!  Last year (for 2018) the IRS put out some late changes and some early filers got tax due notices after they got their refund.  Also if you file in an early batch they get stuck in processing and might even take longer to get your refund.  

And You should wait because you might get a late W2 or 1099 in the mail.  They have until Jan 31 to send you the tax forms.  Or they may send you a corrected W2 or 1099 even later.
