The ten percent (10%) penalty for early withdrawal from your IRA can be eliminated for total and permanent disability of the participant/IRA owner. Even though you didn't receive the social security disability officially until 2017, you can use that as your reason for taking the money early. The IRA will still be taxable, but the penalty can be eliminated.
