Can the LTD company make me go to court even though I am working again? If SSD determines that I was not disabled, is it possible that I can still get money from my LTD carrier for the time when I was sick and not working?

Nobody can "make you go to court."  If you are working again, your long-term disability insurance payments may be terminated, as this is evidence that you do not meet the definition of disability in your plan.  You may still be eligible for long-term disability payments even though Social Security has determined that you are not disabled under their standards.  The standards for your long-term disability insurance company Social Security disability are different.
