Where is my other 4 w2

What do you mean the other 4 W-2?

Did you not enter all of your 2019 W-2's on the 2019 tax return that you filed with the IRS?

And you only get 1 Refund for the total income from all the W2s.  You don't get a refund for each W2.  And by adding more income your refund can go down.
