The reference to line 7 of form 1040, for scholarship income, is from 2017 and earlier.
Today, it goes on line 8r of Schedule 1.
Enter at Educational Expenses and Scholarships, under Deductions and credits (not in the income section). After answering no to having a 1098-T, answer yes to qualifying for an exception (that gets you to the entry screens). You may have to go thru the whole education interview to get to the scholarship screen.
If you have a 1098-T, enter it. You will eventually be asked if you had scholarship not shown on the 1098-T. Then you will be asked if any of it was used for room and board (R&B). Enter the amount of the stipend. R&B are not "qualified expenses". So, this is how you tell TT that it's taxable. Note the wording at that screen “or other expenses”. You didn’t have to literally use the scholarship for R&B. This will put it on line 8r of Schedule 1.
