I have a client that did not include the 1098-T in her 2017  tax return. She wants to now include it which would increase her refund by $1,712. I inputted all the information for the 1040X but the refund monitor does not show a refund and also it has DO NOT FILE on it. How do I generate the 1040X so I can have it signed and mail it to the IRS? Am I doing something wrong?
