My multi-member LLC is incorporated in Delaware, but my home address is in Massachusetts and I go to school in Indiana. How do I file?

My LLC is registered in Delaware and we pay franchise tax there. My home address is in Massachusetts. However, I go to school in Indiana for 9 months out of the year and pay rent there. The other member lives in MA and goes to school in NH. Our business is 100% online - we do not have any business expenses relating to physical products or services. I assume I will need to pay MA income taxes because that is the location of my residence. Do I need to file a LLC return in MA or DE? How does Indiana fit into the situation since I am there for most of the year?
