Earned Income Allocation for Part Year Resident

In most cases yes- but you may still have to enter the amount from the W2 in TurboTax for the state return.  Just make sure that the amounts add up to the total- in rare cases (New York for example) the State Wages in Box 15 and not necessarily the NY state wages.  

So if I am understanding this correctly, I just need to file for each state return without allocation because they are already split. Thanks for confirming!
