No one can see your tax return. We do not know why you are in a higher bracket---but the usual reason would be a higher income. There are no special federal tax breaks or deductions for being disabled except for the higher standard deduction for legal blindness.
We cannot see what credits or deductions you entered so we cannot know if you missed anything. A good way to check would be to print 2023 and 2022 and lay them side by side to compare line by line and see what is different.
And....please check all of your data entries for accuracy. Make sure you did not have any typos, extra zeros or misplaced decimals when you entered amounts.
