You will be able to check in your bags at Chicago union Station any time after 8am on the day of travel. (When the checked luggage counter opens for the day).
As for carry on storage on top of the paid option above you will be able to store your bags in Metropolitan Lounge which you will have access to if you are traveling in a sleeper. There will be no fee there but a tip to the bag room attendant is encouraged.
