I am not completely sure if I did my state taxes right. Can I get some help with my state returns?

If you can provide details:  what are the states involved and what did you have a question about.  Also, which state do you live in?

I was in California from Jan to May. From June to December I was in Massachusetts. My employer was in Massachusetts the whole time. I'm not sure who do I owe state taxes for the first part of the year.

[arihantb2]

My w2 says that my company paid taxes to California for the first part of the year.

[DanielV01]

Yes.  By filing a part-year return to California, the tax you paid to California will be reconciled with California..  Your W-2 is correctly stated.

[DanielV01 · Accepted solution]

You will file part-year resident returns for California and Massachusetts.  Thankfully, your company is reporting your income correctly on your W2.  You will pay tax to California on the income you earned in California, and you pay tax to Massachusetts on the income you earn in Massachusetts.  Each state will have an allocation or an apportionment screen regarding your income to verify that each state is using the correct amount of income to determine your tax.

Both states will pretend that all of your income is taxable in their state, and then prorate your tax to the amount of income actually earned in the state, but California will not tax Massachusetts' income and Massachusetts will not tax California's income.

On each state return, make sure you include your residency periods.  For California, it was from January 1, 2018, until your move-out day in May, and for Massachusetts, it was from that day in May until December 31, 2018.
