I would like to know how to first check the immigration information schedule at the U.S. Consulate? My husband has submitted documents to the U.S. Consulate for 5 months, but now

Are you applying for an immigrant visa for a citizen’s spouse? If yes, if there is no news for 5 months, it is a long time. You can send an email to the embassy or call the embassy for consultation. It may be that the email address you left was not written clearly and they sent it to the wrong email address. Generally, for CR1/IR1 visas submitted domestically, you will definitely receive an email within 2-3 months, asking you to submit the confirmation page of the DS-260 form and a copy of your passport. You can check the email address you originally left and the trash can of your email address. If not, contact the embassy as soon as possible. There was an applicant before but the email address sent by the embassy was wrong, so they never received the P3.
