See if you can find Business Tax under Other Tax Situations and go though the Self Employment Tax. Only thing I can think of is if you have any depreciation that transferred from 2022 that you are not counting. Or any other expenses that carried over that you forgot. Better look at your schedule C and see what's on it. Are you using the Online version?
Before filing you can preview the 1040 or print the whole return. You have to pay any fees first before you can see all the forms, etc.
