Without knowing which states you are referring to, and whether or not those states have an income tax reporting requirement, it's difficult to fully answer your question. The simple response is that you will file all income in your current resident state, since you have not officially moved (assuming it has income tax).
Also, since you had extended stays in other states, you will need to file a non-resident tax return for income earned in the other state. Your current resident state may offer a credit for taxes paid to the other state.
This article might be helpful for multiple state situations. And check this out too about when you would have to file in more than one state.
