You said your employment lasted 11.5 months, but you didn't say when you were terminated.
So, I can't tell you if you are too late. Don't wait for a 3rd party controlled by your employer to act. File a charge wit the EEOC or the Maryland Commission on Civil Rights.
It is better to follow the directions set out for filing a written a written charge. If you don't do it online, send it by mail, certified mail, return receipt.
I've provided a link to the Maryland site. It also gives you information on the EEOC.

You have 300 days from the date of termination to file a charge with the EEOC; and that is filing a charge, not completing the intake questionnaire - the latter will get you nowhere. After completing the intake questionnaire, you must then sign and file a charge to stop the 300 days from expiring. It seems that you may have a claim for discrimination as under the American Disabilities Act. Contact the EEOC immediately.
