Part-Year Resident from PA to OK

[seekingassistance]

Hey guys, I am looking for some input and trying to better understand if this is just how it is or if there is something I could be doing differently to get a different result. 

I am filing my taxes and the result I am getting from entering my info as prompted on TaxAct are telling me I am going to owe over $1k in state taxes, and based on some preliminary reading I've been doing I am confident this is due to part-year residency. I lived and worked in Pennsylvania from until September of this year, and then I moved to Oklahoma and began living and working here in October. 

I am hoping someone can break it down for me to explain why, and also tell me if this is just how it's gonna be, or if there is a different way I can enter the information or a different service I can use to avoid this outcome. Reading on the forums here I got the impression that TurboTax lets you differentiate between the income earned in one state or the other, but some other services (like TaxAct that I was using) may not. Thanks in advance for all useful info.

In general, if you lived and worked in one state for part of the year and then you moved and worked in another state for the rest of the year, then you would file two part-year resident state tax returns.  Each state would tax money earned while you lived in that state and/or money earned from working in that state.  It can get more complicated if you are living in one state while working in another, but TurboTax can help you work through either situation.  I do not know how other tax software may handle multi-state returns.

You can start your return for free using TurboTax Online to see if you get a different result.  You are not obligated to pay for the return until you choose to file it.

Take a look at the following TurboTax help article to learn more about filing multi-state returns:
