Will my 2016 1040 form provide the PIN I need in n order to e-file my 2018 W-2?

No.  You will need your AGI from your 2017 tax return.  There is nothing on your 2016 tax return that will assist in e-filing your 2018 tax return.   And your W-2 is just one small piece of your 2018 tax return; make sure you include everything as you can only file 1 tax return per year!   https://ttlc.intuit.com/replies/3301618
