I need to change like 47 on my 1040

Line 47?  What year?  There is no line 47 on a 2021 1040 return.

Did you already file the tax return?   And what tax year are you asking about?  There is no line 47 on a 2021 Form 1040.   Are you asking about a state return?   Or a line on some other form or schedule?   What exactly is it that you want to change?
