So if my income, 1099-NEC and 401k is over the standard deduction then I have to pay taxes on it even though i'm 80??
Yes, with the additional proviso that your income may also make your social security taxable. And you have to pay self-employment tax on the 1099-NEC income even if it is less than the standard deduction.
You can use this IRS web site.

If the 1099-NEC is not from self-employment (consulting, a side gig, etc) then we can discuss whether it should be "other income" (like a hobby), which is taxable income but not subject to the additional SE tax. But we would need more details about what you did to get that money.
