Why are you asking that question? What are you trying to do?
The term "estimated yearly income" does not exist on the personal income tax form 1040. So, as others have indicated, the answer to you question depends on why you need the info.
Line 7b is your total (reportable) income*
Line 8b is your Adjusted Gross Income (AGI)
Line 11b is your Taxable income (after all deductions and adjustments)
*This is most likely the amount you are looking for. But "estimated" seems to indicate you really want the 2020 amount, not the 2019. Only you can provide that.
