On the "Your 2021 self-employed work summary" page: Does the 2021 amount for each "line of work" include the deductions for expenses? (The amount does not match 1099-NEC)

"Your 2021 self-employed work summary" reflects your net profit.  That will be all of the income less all of your expenses.  It is probable that it will not match your 1099-NEC.

Thank you!!!!
