Unfortunately, you have no safeties. Safeties are schools where you will be accepted, which you can afford, and where you will be happy to attend. Many schools might accept you but will not give you enough financial aid to make them affordable to you.
Unfortunately (#2), Massachusetts is not a state that gives instate tuition or FA to undocumented students who graduate from their high schools. Check to see if there are any community colleges in your area that might be affordable to you.
There have been cases in California where an undocumented student has attended college and been able to get a professional license (law, medical) without documentation, but they are very rare. DACA students have SSNs and can legally work, but you cannot. You need to look at other options because as it stands right now, you would go to school for 4 years and end up where you are now - undocumented and unable to work in the USA.
If Canada or India are options, look at those. School in Massachusetts is just not a good option right now. MIT is giving you boilerplate answers, that IF you are accepted they will work with you to get the CSS completed. That doesn’t mean there will be a pot of money for you but they will HELP you get the documents they need. I have to agree with those above that if your parents are required to file taxes, they will need to do so. You said your sister has a tax ID number and that’s what your parent(s) would need to file too.
