Bank of America Froze Assets and withdrawals after 4 years Nationwide

I have been transferring money back and forth between my checking and savings for over 4 years. Just recently the bank froze my account from any withdrawals because they realized (and I had forgotten) that the original account was opened as a Coogan account. When the savings accounts showed up on my online banking account I for some reason thought that they were converted to savings accounts. Well the last deposits I made were in total of $10K. Only about $15 dollars was deposited in my daughters name from one acting gig. Is there anything I can do to withdraw the money that is rightfully mine because I had been transferring in and out several thousands of dollars at a time and now all of a sudden Bank of America put a stop to it.
