The short answer is yes, you must continue paying child support. Earning disability benefits does not eliminate your financial obligations including child support. You must make the payments that were directed by the court. Failure to do so can result in serious consequences.
The amount of your monthly disability benefits is likely to be less than what you used to earn, but child support orders aren’t just automatically recalculated based on your new financial situation. You must request a modification in your child support order by petitioning the court.
