On a 2020 federal tax return Form 1040 your Total Income in on Line 9.  The Adjusted Gross Income is on Line 11.  Taxable Income is on Line 19.

Note that total income on Line 9 of your 1040 (1040- SR) will not include tax-exempt income, the non-taxable amount of income from certain retirement benefits, etc.

Gross income is defined as all income from whatever source derived per Section 61 of the tax code.

We need to know what you are really trying to ask about--just in case.      If you are trying to find your adjusted gross income from 2019 so you can enter AGI to e-file 2020, look on your 2019 return line 8b.
