Do i have to also file for social security tax where it says nonfarm option on my delivery income to get all my social security credits?

We cannot see your tax return or your screen.  What delivery income?  Were you delivering Instacart, DoorDash, Grubhub----or something like that?   That is self-employment income and yes, you have to enter that income on your tax return and pay self-employment tax for Social Security and Medicare.   I do not understand where you are seeing "nonfarm" --please explain that.  

If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare,  you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
