Per IRS Instructions for Form 1098-T, Tuition Statement, on page 3:
Instructions for Student
You, or the person who can claim you as a dependent, may be able to claim an education credit on Form 1040 or 1040-SR. This statement has been furnished to you by an eligible educational institution in which you are enrolled, or by an insurer who makes reimbursements or refunds of qualified tuition and related expenses to you. This statement is required to support any claim for an education credit. Retain this statement for your records. To see if you qualify for a credit, and for help in calculating the amount of your credit, see Pub. 970, Form 8863, and the Instructions for Forms 1040 and 1040-SR
Your institution must include its name, address, and information contact telephone number on this statement. It may also include contact information for a service provider. Although the filer or the service provider may be able to answer certain questions about the statement, do not contact the filer or the service provider for explanations of the requirements for (and how to figure) any education credit that you may claim.
Student’s taxpayer identification number (TIN). For your protection, this form may show only the last four digits of your TIN (SSN, ITIN, ATIN, or EIN). However, the issuer has reported your complete TIN to the IRS. Caution: If your TIN is not shown in this box, your school was not able to provide it. Contact your school if you have questions.
Account number. May show an account or other unique number the filer assigned to distinguish your account.

Box 4. Shows any adjustment made by an eligible educational institution for a prior year for qualified tuition and related expenses that were reported on a prior year Form 1098-T.
