Ask your employer if the 12/31 pay will be on a 2019 W2 or be considered a payment in January 2020. Sometimes the last pay period of the year is paid in January even if you get the deposit a couple days early. They have until Jan 31 to give you a 2019 W2.
Were your other jobs on a W2 or a 1099Misc? Did they take taxes out of your pay? Do you need info on filing a schedule C for Contract Labor 1099Misc?
