ROTC scholarships and monthly stipends are tax free. Since your qualified educational expenses (QEE) are already paid for by ROTC, any other scholarships you have are taxable income to you.
Q. How am I supposed to enter the numbers so I am not paying so much for my refund?
The 1098-T is only an informational document. The numbers on it are not required to be entered onto your tax return. However receipt of a 1098-T frequently means you are either eligible for a tuition credit or possibly the student has taxable scholarship income. The latter applies to you.
You report scholarship income, based on your own financial records, not the 1098-T. In the 1098-T screen, click on the link "What if this is not what I paid the school" underneath box 1. You will then be able to enter the actual amounts paid. You will also reach a screen that allows you to adjust the scholarship amount for "amounts not awarded for 2023 expenses".
Or if you find it easier, just change the numbers in boxes 1& 5 to what your records show. The 1098-T that you enter in TT is not sent to the IRS.
You need to know what the breakdown of that $38,100, in box 5, is and adjust accordingly. It sounds like your monthly stipend may have been mistakenly included.
