You would have to amend your tax return in order to add the 1098-T to your tax return.
Since you have already e-filed the
return, you will need to wait until the IRS has accepted it. Once
they accept it and you have received your refund, then you can amend it by adding the 1098-T.
Once you receive your refund, you can go here https://ttlc.intuit.com/questions/3061514 and get instructions for amending.
And the instructions are here https://ttlc.intuit.com/questions/2562661 for where to enter the Form 1098-T when you are
amending the return.
NOTE: Your 1098-T may qualify you for
education-related tax benefits like the American Opportunity Credit, Lifetime
Learning Credit, or the Tuition and Fees Deduction. The software will choose
the one that will provide you the biggest federal tax benefit, if you qualify
for any of those benefits.
