Message I left UK volantarily on Dec 2017. Prior to leave UK i received deportation letter. I overstayed in UK. Should I discolse this to DS160 form?

You have stated that your overstay action in the UK was a crime. If so, it needs to be disclosed on the DS-160 nonimmigrant visa form. The consular officer will consider it in the adjudication of the nonimmigrant visa and weigh in his or her mind whether you are trustworthy enough to leave the US when your authorized period of stay expires taking into account your actions in complying with the immigration laws of the UK.
