S.S.
Don't give your SSN to the school. If they say they need it because it's your student ID number, tell them to assign you a student ID number. Bottom line, they're not allowed to require you to give them the number unless they're giving YOU money (financial aid); in which case they're required to report it as income to the IRS.
DO apply to recognized, accredited brick-and-mortar schools which have online degree programs. A degree from an online school with no reputation or a bad reputation won't help you much, and could be a huge waste of time and money. It may be that as a student of a brick-and-mortar school, you have access to the college health care facilities, resources and perhaps insurance coverage.
If your ultimate career goal is to be a Certified Public Accountant (CPA), research what the requirements are in your state. It may be that no degree is needed; perhaps you can self-educate, then take and pass a test to become a CPA.
Once you've chosen a school, DO apply for every scholarship and grant you can find which will apply to you. It just may be that you can line up enough financial aid to quit your second job.
Aim for the highest-quality college at which to study; the most financial aid (grants and scholarships - avoid debt!); and the least amount of required coursework to achieve your career goal.
I don't know what your current two jobs are, but if you're aiming for an accounting career, consider getting a job (not a third! - replace your second) as a bookkeeper. Many times you can learn accounting basics under the tutelage of someone else as a bookkeeper. It's even possible to get a work-from-home job doing bookkeeping work. This would be career-building work experience and if work-from-home would make your college studies and child care much more feasible.
