Yes you might have 3 W2s to enter into your return. You tax return is based on your total income for the year not time worked.
The W2 is for what you were actually paid in 2019, not when you worked. So as I said the last time period you worked in December might be actually paid and dated the first week of January (even if you got it in Dec). Like my husband gets paid on Jan 1 for December even though he gets the Direct Deposit a couple days earlier in Dec. Ask your employer or wait and see if you get a W2 for it.
