If your cosmetology school issued you a 1098-T, you should have received it by now. Some schools have this information available to you through their web site.
Since the school is probably closed, currently, you will need to wait until they reopen, or until the IRS processes all the information sent to them with your Social Security number and has it available for you to get from them.
The IRS will not have this information available possibly until June of 2020.
